How to Solve Environment.getExternalStorageDirectory() in android Q(10) [duplicate] - android-10.0

Question

Working on android Java, recently updated SDK to API level 29 now there is a warning shown which states that
Environment.getExternalStorageDirectory() is deprecated in API level 29
My code is
private void saveImage() {
if (requestPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
final String folderPath = Environment.getExternalStorageDirectory() + "/PhotoEditors";
File folder = new File(folderPath);
if (!folder.exists()) {
File wallpaperDirectory = new File(folderPath);
wallpaperDirectory.mkdirs();
}
showLoading("Saving...");
final String filepath=folderPath
+ File.separator + ""
+ System.currentTimeMillis() + ".png";
File file = new File(filepath);
try {
file.createNewFile();
SaveSettings saveSettings = new SaveSettings.Builder()
.setClearViewsEnabled(true)
.setTransparencyEnabled(true)
.build();
if(isStoragePermissionGranted() ) {
mPhotoEditor.saveAsFile(file.getAbsolutePath(), saveSettings, new PhotoEditor.OnSaveListener() {
#Override
public void onSuccess(#NonNull String imagePath) {
hideLoading();
showSnackbar("Image Saved Successfully");
mPhotoEditorView.getSource().setImageURI(Uri.fromFile(new File(imagePath)));
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,Uri.fromFile(new File(filepath))));
Intent intent = new Intent(EditImageActivity.this, StartActivity.class);
startActivity(intent);
finish();
}
#Override
public void onFailure(#NonNull Exception exception) {
hideLoading();
showSnackbar("Failed to save Image");
}
});
}
What will be the alternative for this?

Answer 1

Use getExternalFilesDir(), getExternalCacheDir(), or getExternalMediaDirs() (methods on Context) instead of Environment.getExternalStorageDirectory().
Or, modify mPhotoEditor to be able to work with a Uri, then:
Use ACTION_CREATE_DOCUMENT to get a Uri to a location of the user's choosing, or
Use MediaStore, ContentResolver, and insert() to get a Uri for a particular type of media (e.g., an image) — see this sample app that demonstrates doing this for downloading MP4 videos from a Web site
Also, note that your Uri.fromFile with ACTION_MEDIA_SCANNER_SCAN_FILE should be crashing on Android 7.0+ with a FileUriExposedException. On Android Q, only the MediaStore/insert() option will get your content indexed by the MediaStore quickly.
Note that you can opt out of these "scoped storage" changes on Android 10 and 11, if your targetSdkVersion is below 30, using android:requestLegacyExternalStorage="true" in the <application> element of the manifest. This is not a long-term solution, as your targetSdkVersion will need to be 30 or higher sometime in 2021 if you are distributing your app through the Play Store (and perhaps elsewhere).

Answer 2

Get the destPath with the new API call:
String destPath = mContext.getExternalFilesDir(null).getAbsolutePath();

Answer 3

For Android Q, you can add android:requestLegacyExternalStorage="true" to your element in the manifest. This opts you into the legacy storage model, and your existing external storage code will work.
<manifest ... >
<!-- This attribute is "false" by default on apps targeting
Android 10 or higher. -->
<application android:requestLegacyExternalStorage="true" ... >
...
</application>
</manifest>
Technically, you only need this once you update your targetSdkVersion to 29. Apps with lower targetSdkVersion values default to opting into legacy storage and would need android:requestLegacyExternalStorage="false" to opt out.

Answer 4

Please use getExternalFilesDir(), getExternalCacheDir() instead of Environment.getExternalStorageDirectory() when you creating file in Android 10.
See below line:
val file = File(this.externalCacheDir!!.absolutePath, "/your_file_name")

Answer 5

This is a small example how to get URI for a file if you want to take photo using default camera and store it in a DCIM folder (DCIM/app_name/filename.jpg):
Open camera (remember about CAMERA permission):
private var photoURI: Uri? = null
private fun openCamera() {
Intent(MediaStore.ACTION_IMAGE_CAPTURE).also { takePictureIntent ->
photoURI = getPhotoFileUri()
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI)
takePictureIntent.resolveActivity(requireActivity().packageManager)?.also {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE)
}
}
}
And get URI:
private fun getPhotoFileUri(): Uri {
val timeStamp = SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault()).format(Date())
val fileName = "IMG_${timeStamp}.jpg"
var uri: Uri? = null
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
val resolver = requireContext().contentResolver
val contentValues = ContentValues().apply {
put(MediaStore.MediaColumns.DISPLAY_NAME, fileName)
put(MediaStore.MediaColumns.MIME_TYPE, "image/jpeg")
put(MediaStore.MediaColumns.RELATIVE_PATH, "DCIM/app_name/")
}
uri = resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)
}
return uri ?: getUriForPreQ(fileName)
}
private fun getUriForPreQ(fileName: String): Uri {
val dir = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DCIM)
val photoFile = File(dir, "/app_name/$fileName")
if (photoFile.parentFile?.exists() == false) photoFile.parentFile?.mkdir()
return FileProvider.getUriForFile(
requireContext(),
"ru.app_name.fileprovider",
photoFile
)
}
Don't forget about WRITE_EXTERNAL_STORAGE permission for pre Q and add a FileProvider to AndroidManifest.xml.
And get a result:
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
when (requestCode) {
REQUEST_IMAGE_CAPTURE -> {
photoURI?.let {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
val thumbnail: Bitmap =
requireContext().contentResolver.loadThumbnail(
it, Size(640, 480), null
)
} else {
// pre Q actions
}
}
}
}
}

Answer 6

This worked for me
Add this line in application tag of manifest file
android:requestLegacyExternalStorage="true"
Example
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:networkSecurityConfig="#xml/network_security_config"
android:requestLegacyExternalStorage="true"
android:supportsRtl="true"
android:theme="#style/AppTheme">
</application>
Target SDK is 29
defaultConfig {
minSdkVersion 16
targetSdkVersion 29
multiDexEnabled true
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

Answer 7

To get internal storage directory without hard coding,
Permissions (For all Android versions). Don't forget to get permissions from the user.
Request all files access
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" android:maxSdkVersion="29" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="29" />
<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" tools:ignore="ScopedStorage" />
Legacy permission for Android 10 (add this to AndroidManifest.xml > application tag).
android:requestLegacyExternalStorage="true"
Get internal storage directory path:
public static String getInternalStorageDirectoryPath(Context context) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
StorageManager storageManager = (StorageManager) context.getSystemService(Context.STORAGE_SERVICE);
return storageManager.getPrimaryStorageVolume().getDirectory().getAbsolutePath();
} else {
return Environment.getExternalStorageDirectory().getAbsolutePath();
}
}

Answer 8

This worked
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
contentResolver?.also { resolver ->
val contentValues = ContentValues().apply {
put(MediaStore.MediaColumns.DISPLAY_NAME, "Image_"+".jpg")
put(MediaStore.MediaColumns.MIME_TYPE, "image/jpg")
put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_PICTURES + File.separator+ "TestFolder")
}
val imageUri: Uri? = resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)
fos = imageUri?.let { resolver.openOutputStream(it) }
bitmap.compress(Bitmap.CompressFormat.JPEG,100,fos)
Objects.requireNonNull(fos)
}
}

Answer 9

You could make use of StorageManager & StorageVolume classes
StorageVolume.getPrimaryStorageVolume(): This volume is the same storage device returned by Environment#getExternalStorageDirectory() and Context#getExternalFilesDir(String).
public String myGetExternalStorageDir() {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R)
return getPrimaryStorageVolumeForAndroid11AndAbove();
else
return getPrimaryStorageVolumeBeforeAndroid11();
}
#TargetApi(Build.VERSION_CODES.R)
private String getPrimaryStorageVolumeForAndroid11AndAbove() {
StorageManager myStorageManager = (StorageManager) ctx.getSystemService(Context.STORAGE_SERVICE);
StorageVolume mySV = myStorageManager.getPrimaryStorageVolume();
return mySV.getDirectory().getPath();
}
private String getPrimaryStorageVolumeBeforeAndroid11() {
String volumeRootPath = "";
StorageManager myStorageManager = (StorageManager) ctx.getSystemService(Context.STORAGE_SERVICE);
StorageVolume mySV = myStorageManager.getPrimaryStorageVolume();
Class<?> storageVolumeClazz = null;
try {
storageVolumeClazz = Class.forName("android.os.storage.StorageVolume");
Method getPath = storageVolumeClazz.getMethod("getPath");
volumeRootPath = (String) getPath.invoke(mySV);
} catch (Exception e) {
e.printStackTrace();
}
return volumeRootPath;
}

private fun saveImage(bitmap: Bitmap, name: String) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
val resolver = contentResolver
val contentValues = ContentValues()
contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, name)
contentValues.put(MediaStore.MediaColumns.MIME_TYPE, "image/png")
contentValues.put(MediaStore.MediaColumns.RELATIVE_PATH, "DCIM/" + "YOUR_FOLDER")
val imageUri =
resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues)
val fos = resolver.openOutputStream(imageUri!!)
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos)
fos!!.flush()
fos.close()
toast("Saved to gallery")
} else {
if (isPermissionGranted(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
val imagesDir = Environment.getExternalStoragePublicDirectory(
Environment.DIRECTORY_DCIM
).toString() + File.separator + "YOUR_FOLDER"
if (!file.exists()) {
file.mkdir()
}
val image = File(imagesDir, "$name.png")
val fos = FileOutputStream(image)
bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos)
fos.flush()
fos.close()
} else {
// ask for permission
}
}
}

Answer 11

Recently I also face similar kind of issues, Due to my code was large and i don't want to add new functionality in existing code so i just simply change path..
Environment.getExternalStorageDirectory() Replace with
context.getExternalFilesDir(null).getAbsolutePath()
Code
private void saveImage() {
if (requestPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
final String folderPath = this.getExternalFilesDir(null).getAbsolutePath() + "/PhotoEditors";
File folder = new File(folderPath);
if (!folder.exists()) {
File wallpaperDirectory = new File(folderPath);
wallpaperDirectory.mkdirs();
}
showLoading("Saving...");
final String filepath=folderPath
+ File.separator + ""
+ System.currentTimeMillis() + ".png";
File file = new File(filepath);
try {
file.createNewFile();
SaveSettings saveSettings = new SaveSettings.Builder()
.setClearViewsEnabled(true)
.setTransparencyEnabled(true)
.build();
if(isStoragePermissionGranted() ) {
mPhotoEditor.saveAsFile(file.getAbsolutePath(), saveSettings, new PhotoEditor.OnSaveListener() {
#Override
public void onSuccess(#NonNull String imagePath) {
hideLoading();
showSnackbar("Image Saved Successfully");
mPhotoEditorView.getSource().setImageURI(Uri.fromFile(new File(imagePath)));
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE,Uri.fromFile(new File(filepath))));
Intent intent = new Intent(EditImageActivity.this, StartActivity.class);
startActivity(intent);
finish();
}
#Override
public void onFailure(#NonNull Exception exception) {
hideLoading();
showSnackbar("Failed to save Image");
}
});
}

Answer 12

var tempDir: File = inContext.getExternalFilesDir("/")!!
tempDir = File(tempDir.getAbsolutePath().toString() + "/.IncidentImages/")
tempDir.mkdir()

Answer 13

If you work with XAMARIN and are confused by all this different answers (like me) just follow this example:
var picture = new Java.IO.File(Environment.DirectoryPictures, "fileName");
Took me some time to figure this out.
