Did you set the permission in the manifest? You can do that by implementing this code:
<manifest ... >
<uses-permission android:name="android.permission.RECORD_AUDIO"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.STORAGE"/>
...
</manifest>

Screen recording app does not work on Android 10

I have an application for recording a screen, it does not work on android version 10. As I understand it, this is due to privacy changes in force in Android 10. Now for any application using MediaProjection api, must specify an attribute android:foregroundServiceType= in the service tag under the manifest, but my application uses MediaProjection in the fragment, not the service. Is it possible to make MediaProjection work from a fragment, or do I need to redo it?
Sorry for my bad english
Here is a mistake
Caused by java.lang.SecurityException

You should use a foreground service inside the fragment to capture the screen.
Find below links for how to use the foreground service to capture the screen.

How to allow multiple windows on webview to get facebook login working?

Android 4.4 WebView file chooser not opening?

We are creating an app which uses the webview and will access a page where the user needs to upload a file. We are experiencing problems with Android 4.4 where the file chooser does not open and clicking the upload button causes nothing to happen. This functionality works with earlier versions using the openFileChooser method like so:
webview.setWebChromeClient(new WebChromeClient() {
//The undocumented magic method override
//Eclipse will swear at you if you try to put #Override here
// For Android 3.0+
public void openFileChooser(ValueCallback<Uri> uploadMsg) {
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");
MainActivity.this.startActivityForResult(Intent.createChooser(i, "File Chooser"), FILECHOOSER_RESULTCODE);
}
// For Android 3.0+
public void openFileChooser(ValueCallback uploadMsg, String acceptType) {
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("*/*");
MainActivity.this.startActivityForResult(
Intent.createChooser(i, "File Browser"),
FILECHOOSER_RESULTCODE);
}
//For Android 4.1
public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture) {
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("image/*");
MainActivity.this.startActivityForResult(Intent.createChooser(i, "File Chooser"), MainActivity.FILECHOOSER_RESULTCODE);
}
});
I have spent a good amount of time searching for a way to do it on 4.4 but have had no luck. Has anyone managed to do this?

This Code worked for me.
private class MyWebChromeClient extends WebChromeClient {
//The undocumented magic method override
//Eclipse will swear at you if you try to put #Override here
// For Android 3.0+
public void openFileChooser(ValueCallback uploadMsg, String acceptType) {
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("*/*");
MainActivity1.this.startActivityForResult(Intent.createChooser(i, "File Browser"), FILECHOOSER_RESULTCODE);
}
//For Android 4.1+ only
protected void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType, String capture)
{
mUploadMessage = uploadMsg;
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("*/*");
startActivityForResult(Intent.createChooser(intent, "File Browser"), FILECHOOSER_RESULTCODE);
}
protected void openFileChooser(ValueCallback<Uri> uploadMsg)
{
mUploadMessage = uploadMsg;
Intent i = new Intent(Intent.ACTION_GET_CONTENT);
i.addCategory(Intent.CATEGORY_OPENABLE);
i.setType("*/*");
startActivityForResult(Intent.createChooser(i, "File Chooser"), FILECHOOSER_RESULTCODE);
}
// For Lollipop 5.0+ Devices
public boolean onShowFileChooser(WebView mWebView, ValueCallback<Uri[]> filePathCallback, WebChromeClient.FileChooserParams fileChooserParams) {
if (uploadMessage != null) {
uploadMessage.onReceiveValue(null);
uploadMessage = null;
}
uploadMessage = filePathCallback;
Intent intent = null;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
intent = fileChooserParams.createIntent();
}
try {
startActivityForResult(intent, REQUEST_SELECT_FILE);
} catch (ActivityNotFoundException e) {
uploadMessage = null;
Toast.makeText(getApplicationContext(), "Cannot Open File Chooser", Toast.LENGTH_LONG).show();
return false;
}
return true;
}
#Override
public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
Log.d("LogTag", message);
result.confirm();
return true;
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_SELECT_FILE) {
if (uploadMessage == null) return;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
uploadMessage.onReceiveValue(WebChromeClient.FileChooserParams.parseResult(resultCode, data));
}

} else if (requestCode == FILECHOOSER_RESULTCODE) {

return;

}
}

WebView is working as intended
If I understand correctly what the above link says , you (me and probably some hundreds more developers) are looking for a hack

Have a look this. Because api 19 4.4, webview has been migrated to use Chromium, not WebChromeClient anymore.

I was working on this issue too, and the problem and here is my solution
private class MyWebChromeClient extends WebChromeClient {
/**
* This is the method used by Android 5.0+ to upload files towards a web form in a Webview
*
* #param webView
* #param filePathCallback
* #param fileChooserParams
* #return
*/
#Override
public boolean onShowFileChooser(
WebView webView, ValueCallback<Uri[]> filePathCallback,
WebChromeClient.FileChooserParams fileChooserParams) {

One problem that I solved is the uri delivered for the onActivityResult() method does not have extension. To solve this I use this method
public static Uri savePicture(Context context, Bitmap bitmap, int maxSize) {
int cropWidth = bitmap.getWidth();
int cropHeight = bitmap.getHeight();
if (cropWidth > maxSize) {
cropHeight = cropHeight * maxSize / cropWidth;
cropWidth = maxSize;
}
if (cropHeight > maxSize) {
cropWidth = cropWidth * maxSize / cropHeight;
cropHeight = maxSize;
}
bitmap = ThumbnailUtils.extractThumbnail(bitmap, cropWidth, cropHeight, ThumbnailUtils.OPTIONS_RECYCLE_INPUT);
File mediaStorageDir = new File(
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),
context.getString(R.string.app_name)
);
if (!mediaStorageDir.exists()) {
if (!mediaStorageDir.mkdirs()) {
return null;
}
}
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
File mediaFile = new File(
mediaStorageDir.getPath() + File.separator + "IMG_" + timeStamp + ".jpg"
);
// Saving the bitmap
try {
ByteArrayOutputStream out = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 80, out);
FileOutputStream stream = new FileOutputStream(mediaFile);
stream.write(out.toByteArray());
stream.close();
} catch (IOException exception) {
exception.printStackTrace();
}
// Mediascanner need to scan for the image saved
Intent mediaScannerIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
Uri fileContentUri = Uri.fromFile(mediaFile);
mediaScannerIntent.setData(fileContentUri);
context.sendBroadcast(mediaScannerIntent);
return fileContentUri;
}
Finally, onActivityResult() method is
#Override
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
if (resultCode == RESULT_OK) {
// This is for Android 4.4.4- (JellyBean & KitKat)
if (requestCode == FILECHOOSER_RESULTCODE) {
if (null == mUploadMessage) {
super.onActivityResult(requestCode, resultCode, intent);
return;
}
final boolean isCamera;
if (intent == null) {
isCamera = true;
} else {
final String action = intent.getAction();
if (action == null) {
isCamera = false;
} else {
isCamera = action.equals(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
}
}
Uri selectedImageUri;
if (isCamera) {
selectedImageUri = mOutputFileUri;
mUploadMessage.onReceiveValue(selectedImageUri);
mUploadMessage = null;
return;
} else {
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), intent.getData());
selectedImageUri = intent == null ? null : ImageUtility.savePicture(this, bitmap, 1400);
mUploadMessage.onReceiveValue(selectedImageUri);
mUploadMessage = null;
return;
} catch (IOException e) {
e.printStackTrace();
}
}
// And this is for Android 5.0+ (Lollipop)
} else if (requestCode == INPUT_FILE_REQUEST_CODE) {
Uri[] results = null;
// Check that the response is a good one
if (resultCode == Activity.RESULT_OK) {
if (intent == null) {
// If there is not data, then we may have taken a photo
if (mCameraPhotoPath != null) {
results = new Uri[]{Uri.parse(mCameraPhotoPath)};
}
} else {
Bitmap bitmap = null;
try {
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), intent.getData());
} catch (IOException e) {
e.printStackTrace();
}
Uri dataUri = ImageUtility.savePicture(this, bitmap, 1400);
if (dataUri != null) {
results = new Uri[]{dataUri};
}
}
}
mFilePathCallback.onReceiveValue(results);
mFilePathCallback = null;
return;
}
} else {
super.onActivityResult(requestCode, resultCode, intent);
return;
}
}

Found a solution that worked for me. I've added one more rule in proguard-android.txt:
-keepclassmembers class * extends android.webkit.WebChromeClient {
public void openFileChooser(...);
}

Android Kotlin,
MyWebViewChromeClient class:
class MyWebViewChromeClient(private val mContext: MyMainActivity): WebChromeClient() {
override fun onShowFileChooser(webView: WebView, filePathCallback: ValueCallback<Array<Uri>>, fileChooserParams: FileChooserParams): Boolean {
mContext.mUploadMessageArray?.onReceiveValue(null)
mContext.mUploadMessageArray = filePathCallback
val contentSelectionIntent = Intent(Intent.ACTION_GET_CONTENT)
contentSelectionIntent.addCategory(Intent.CATEGORY_OPENABLE)
contentSelectionIntent.type = "*/*"
val intentArray: Array<Intent?> = arrayOfNulls(0)
val chooserIntent = Intent(Intent.ACTION_CHOOSER)
chooserIntent.putExtra(Intent.EXTRA_INTENT, contentSelectionIntent)
chooserIntent.putExtra(Intent.EXTRA_TITLE, "File Chooser")
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray)
mContext.startActivityForResult(chooserIntent, mContext.FILECHOOSER_RESULTCODE)
return true
}
MyMainActivity class:
class MyMainActivity : MyBaseActivity() {
val FILECHOOSER_RESULTCODE = 1001
var mUploadMessageArray: ValueCallback<Array<Uri>>? = null
private lateinit var mWebView: MyWebView
private lateinit var mContext: Context
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
if (requestCode == FILECHOOSER_RESULTCODE) {
if (mUploadMessageArray == null) {
return
}
val result = if (intent == null || resultCode != Activity.RESULT_OK) null else data?.data
result?.let {
val uriArray: Array<Uri> = arrayOf(it)
mUploadMessageArray?.onReceiveValue(uriArray)
mUploadMessageArray = null
} ?: kotlin.run {
mUploadMessageArray?.onReceiveValue(null)
mUploadMessageArray = null
}
}
}
}

What I have done to fix this problem it is to implement CrossWalk into my project. I know the size of CrossWalk is significant (adds Chromium to your project) but I really needed this to work fine inside a native app.
I documented how I implemented this in here: http://maurizionapoleoni.de/blog/implementing-a-file-input-with-camera-support-in-android-with-crosswalk/

You need to implement a WebviewClient class. You can check these example .
webview.setWebViewClient(new myWebClient());
The web.setWebChromeClient(new WebChromeClient() {
//
}
Create class called mywebClient and add the following code to implement onPageStarted() function, shouldOvverideLoading() function and onActivityresult() function as shown below.
public class myWebClient extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
}
}
//flipscreen not loading again
#Override
public void onConfigurationChanged(Configuration newConfig){
super.onConfigurationChanged(newConfig);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
if(requestCode==FILECHOOSER_RESULTCODE){
if (null == mUploadMessage) return; Uri result = intent == null || resultCode != RESULT_OK ? null : intent.getData(); mUploadMessage.onReceiveValue(result); mUploadMessage = null;
}
}

I have tried the File Chooser in a webview using the latest Android release 4.4.3, and it's working fine. I guess Google has fixed the issue.
