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);
}

}
// 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) {

}

} else if (requestCode == FILECHOOSER_RESULTCODE) {

return;

mUploadMessage.onReceiveValue(result);
mUploadMessage = null;
}
}
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) {
if (mFilePathCallback != null) {
mFilePathCallback.onReceiveValue(null);
}
mFilePathCallback = filePathCallback;
Intent contentSelectionIntent = new Intent(Intent.ACTION_GET_CONTENT);
contentSelectionIntent.addCategory(Intent.CATEGORY_OPENABLE);
contentSelectionIntent.setType("image/*");
Intent[] intentArray = getCameraIntent();
Intent chooserIntent = new Intent(Intent.ACTION_CHOOSER);
chooserIntent.putExtra(Intent.EXTRA_INTENT, contentSelectionIntent);
chooserIntent.putExtra(Intent.EXTRA_TITLE, "Seleccionar Fuente");
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, intentArray);
startActivityForResult(chooserIntent, INPUT_FILE_REQUEST_CODE);
return true;
}
#Override
public void onProgressChanged(WebView view, int newProgress) {
mProgressBar.setVisibility(View.VISIBLE);
WebActivity.this.setValue(newProgress);
super.onProgressChanged(view, newProgress);
}
#Override
public boolean onJsAlert(WebView view, String url, String message, JsResult result) {
Log.d("LogTag", message);
result.confirm();
return true;
}
/**

public void openFileChooser(ValueCallback<Uri> uploadMsg) {
mUploadMessage = uploadMsg;
Intent i = getChooserIntent(getCameraIntent(), getGalleryIntent("image/*"));
i.addCategory(Intent.CATEGORY_OPENABLE);

public void openFileChooser(ValueCallback uploadMsg, String acceptType) {

}
private Intent[] getCameraIntent() {
// Determine Uri of camera image to save.
Intent takePictureIntent = new Intent(WebActivity.this, CameraActivity.class);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {

takePictureIntent.putExtra("PhotoPath", mCameraPhotoPath);
} catch (IOException ex) {
// Error occurred while creating the File
Log.e(TAG, "Unable to create Image File", ex);
}
// Continue only if the File was successfully created
if (photoFile != null) {

takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,
Uri.fromFile(photoFile));
} else {
takePictureIntent = null;
}
}
Intent[] intentArray;
if (takePictureIntent != null) {
intentArray = new Intent[]{takePictureIntent};
} else {
intentArray = new Intent[0];
}
return intentArray;
}
private Intent getGalleryIntent(String type) {
// Filesystem.
final Intent galleryIntent = new Intent();
galleryIntent.setType(type);
galleryIntent.addCategory(Intent.CATEGORY_OPENABLE);
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
return galleryIntent;
}
private Intent getChooserIntent(Intent[] cameraIntents, Intent galleryIntent) {
// Chooser of filesystem options.
final Intent chooserIntent = Intent.createChooser(galleryIntent, "Seleccionar Fuente");
// Add the camera options.
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents);
return chooserIntent;
}
}
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.

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"/>
...

Sorry for this question, I'm a beginner.
My first app has been rejected due to violating the Device and Network Abuse policy.
Edit: Main reason is that Youtube video doesn't stop playing when the display is turned off...
some info here:
Volating the Device and Network Abuse policy

Anywhere you want inside your Activity class (the one you pasted in your question).
I usually try to order my lifecycle methods in the order Android executes them, so I'd put it after onResume()
#Override
public void onResume() {
super.onResume();
asm_view.onResume(); //remember to add this so your WebView can resume
//Coloring the "recent apps" tab header; doing it onResume, as an insurance
if (Build.VERSION.SDK_INT >= 23) {
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher);
ActivityManager.TaskDescription taskDesc;
taskDesc = new ActivityManager.TaskDescription(getString(R.string.app_name), bm, getColor(R.color.colorPrimary));
MainActivity.this.setTaskDescription(taskDesc);
}
get_location();
}
#Ovveride
public void onPause() {
super.onPause();
asw_view.onPause(); //your WebView variable is asm_view, not mWebView, which is just example code
}
onPause is a lifecycle method of Activity (and Fragments) and can be placed anywhere in the Activity class but putting your lifecycle methods in the order they are executed will help making your code more readable.
I am taking image from camera as well as from gallery,after getting the image, I want to show the image in imageview.
Image that is captured by camera successfully is shown in imageview but when I want to select it from gallery it does not show the image and it also does not show any error. It was working properly but later I add camera feature in activity, it's not working well.

You should check if selectedImage -the bitmap- is null.
I bet selectedImage==null.
This happens if the bitmap would become too big for available memory.
You should scale it down while loading from stream.
Remember: from the camera you only obtain a thumbnail. Thats the difference.

In your code, try to add createScaledBitmap to resize your photo like this:
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
//add this line and use the new bitmap resized
Bitmap imageBitmapResized = Bitmap.createScaledBitmap(imageBitmap , 120, 120, false);
iv.setImageBitmap(imageBitmapResized );
image = encode(imageBitmapResized );//this line is added to encode
} else if (requestCode == PHOTO_FROM_MEMORY_REQUESTED && resultCode == RESULT_OK) {
updateSelectedPicture(data.getData());
}
For some reason outputFileUri returns null in my onActivityResult:
Uri selectedImageUri;
if (isCamera) {
selectedImageUri = outputFileUri;
I don't understand why. Please take a look at my code and see where I go wrong. I let the user take 4 images by choosing from gallery or using the camera. The ones that the user takes with the camera won't show presumably because their uri is null. outputFileUri is a class variable.
