My application share an image but meanwhile the user is sharing the app closes in background. The log is empty, no errors, no warnings. Can you see the error?
try {
fout = new FileOutputStream(imageFile);
bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout);
fout.flush();
fout.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
Uri uri = Uri.fromFile(new File(mPath));
btn1.setVisibility(View.VISIBLE);
btn2.setVisibility(View.VISIBLE);
watermark.setVisibility(View.INVISIBLE);
Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("image/jpeg");
shareIntent.putExtra(android.content.Intent.EXTRA_STREAM, uri);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
startActivity(shareIntent);
} else {
startActivity(Intent.createChooser(shareIntent, "Compartir Vía"));
}
Edit:
The app never crasher, almost continue logging normally, when I open it again backs to begining.

I am developing an Android app. I keep a PDF data in MYSQL database as blob type. I am sending as base64 to Android app. How can I show the pdf in Android app?
As you have the yourBase64String with you, you can convert it to byte array and then save it as file.
FileOutputStream fos = null;
try {
if (yourBase64String != null) {
fos = context.openFileOutput("myPdf.pdf", Context.MODE_PRIVATE);
byte[] decodedString = android.util.Base64.decode(yourBase64String , android.util.Base64.DEFAULT);
fos.write(decodedString);
fos.flush();
fos.close();
}
} catch (Exception e) {
} finally {
if (fos != null) {
fos = null;
}
}
Now after this open this PDF file
Uri path = Uri.fromFile(new File(myPdf.pdf));
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(path, "application/pdf");
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
try {
startActivity(intent);
}
catch (ActivityNotFoundException e) {
Toast.makeText(OpenPdf.this,
"No Application Available to View PDF",
Toast.LENGTH_SHORT).show();
}
Add this permission in your manifest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
I'm trying to pass the screenshot of screen with an explicit intent but the screen shows black screenshot(refer image here). As soon as i click share, a toast appears saying sending failed. Here's the code to capture screenshot and send it to other app:
public void getScreenShot(View view) {
View screenView = view.getRootView();
screenView.setDrawingCacheEnabled(true);
Bitmap bitmap = Bitmap.createBitmap(screenView.getDrawingCache());
screenView.setDrawingCacheEnabled(false);
f = new File(this.getFilesDir(), "screenshotFile");
try {
if (!f.exists())
f.createNewFile();
} catch (IOexception e) {
e.printStackTrace();
}
ByteArrayOutputStream bos = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 10, bos);
byte[] bitmapdata = bos.toByteArray();
FileOutputStream fos = null;
try {
fos = new FileOutputStream(f);
fos.write(bitmapdata);
fos.flush();
fos.close();
} catch (Exception e) {
e.printStackTrace();
}
}
This code sends the data to whatsapp:
public void shareWhatsapp(View view) {
try {
myVib.vibrate(50);
getScreenShot(view);
//String fileName = "screenshotFile";
//Bitmap bitmap = BitmapFactory.decodeFile(f.getAbsolutePath());
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("image/*");
try {
intent.setPackage("com.whatsapp");
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(MainActivity.this, "App not installed", Toast.LENGTH_SHORT).show();
}
//TODO: APP CAN CRASH HERE
if (position > 0) {
try {
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(f);
} catch (Exception e) {
e.printStackTrace();
} finally {
intent.putExtra(Intent.EXTRA_TEXT, Titles.get(position - 1) + ": " + Links.get(position - 1)); //position problems
}
} else {
try {
intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(f);
} catch (Exception e) {
e.printStackTrace();
} finally {
intent.putExtra(Intent.EXTRA_TEXT, Titles.get(0) + ": " + Links.get(0)); //position problems
}
}
startActivity(intent);
} catch (Exception e) {
e.printStackTrace();
}
}
Can someone help me with this?
First, you are writing the file to internal storage. Third-party apps do not have access to your app's internal storage.
Second, you are using Uri.fromFile(), which is starting to be discontinued.
Your safest long-term course of action is to have a ContentProvider serve your file from its location on internal storage, then use a Uri associated with that ContentProvider.
I am trying to use getCropAndSetWallpaperIntent method of WallpaperManager class, but face problems with uri it need. First I tried to get Uri from drawable resourse, but I concluded that this is impossible, and decided to write file to internal storage and get its Uri. Now it gives an error, that uri type must be content. How can I fix this error? Maybe writing file to memory is totally wrong and there are other solutions?
Here is my code:
public void onclick(View v){
switch (v.getId())
{
case R.id.set:
// try{
//R.drawable.file1
File file =new File(this.getFilesDir(),getResources().getResourceName(R.drawable.file1));
file.setWritable(true);
if (!file.exists())
{
Bitmap bm= BitmapFactory.decodeResource(getResources(),R.drawable.file1);
try {
FileOutputStream outputStream=new FileOutputStream(file);
bm.compress(Bitmap.CompressFormat.JPEG,100,outputStream);
outputStream.flush();
outputStream.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
Uri uri=Uri.fromFile(file);
Intent i=wmanager.getCropAndSetWallpaperIntent(uri);
startActivity(i);
break;
case R.id.clear:
try{
wmanager.clear();
}
catch (IOException ioex){
ioex.printStackTrace();
}
}
}
I have seen the same problem, fixed by following method and works fine.
#TargetApi(Build.VERSION_CODES.KITKAT) private void setWallpaperKitkat(File file) {
Uri uri = Uri.fromFile(file);
Intent intent = new Intent(WallpaperManager.ACTION_CROP_AND_SET_WALLPAPER);
String mime = "image/*";
intent.setDataAndType(uri, mime);
try {
startActivity(intent);
} catch (ActivityNotFoundException e) {
//handle error
}
}
I unable to attach Audio file to Some of the Samsung Devices like Samsung GalaxyS2,Nexus etc.I don't know whats the problem.I am able to attach all other devices.Please someone help me for my this issue.My code is as:

Don't set the class name explicitly by calling setClassName(). Instead just set the action, type and extra as described here.
You are assuming that there is ExternalStorage i.e. sd card available on the device. Your S2 or Nexus probably does not have the sd card. I have seen this issue before.
Hi I have a gallery in my app which shows the image in an image view when you click on the thumbnail. I am setting up a Long Click Listener for an alert dialog that has 2 buttons one to set as wallpaper and one to share. I have the share intent and the get drawing cache somewhat working. It works in the emulator but not on my phone. I have used many of the examples on this site to get this going but its not working at all. it keeps force closing the app on my phone. any help is appreciated.
alertDialog.setButton2("Share",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
imgView.setDrawingCacheEnabled(true);
Bitmap b = imgView.getDrawingCache();
File sdCard = Environment.getExternalStorageDirectory();
File file = new File(sdCard.getAbsolutePath() + "image.jpg");
try {
file.createNewFile();
OutputStream fos = null;
fos = new FileOutputStream(file);
b.compress(CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.d("Save Example", "Image saved.");
Intent shareIntent = new Intent(Intent.ACTION_SEND);
Uri phototUri = Uri.parse("file:///sdcard/image.jpg");
shareIntent.setData(phototUri);
shareIntent.setType("image/jpeg");
shareIntent.putExtra(Intent.EXTRA_STREAM, phototUri);
startActivity(Intent.createChooser(shareIntent, "Share Via"));
}
});
alertDialog.show();
return true;
}
});
Update: it seems to be a problem with
b.compress(CompressFormat.JPEG, 95, fos);
it keeps saying null pointer.
Turns out the null pointer is actually a read_only error..So its not actually writing the file i get a ioexception read-only file system. Why is it doing this?
ok here s what i ended up doing to get this to share the pictures in case others need it. It turns out my ImageView was not being rendered as a BitMap so it was make files with nothing in them. So instead i am just calling the drawable from its postion and saving that. Its a lot cleaner code for this simple gallery. I have it in an alert dialog but it can be set to a regular button also.
