Shymaa Othman Answer here working fine as you want
You need to give the permission also in android mainfest
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
also for Android 6.0 and above need runtime permission of WRITE_EXTERNAL_STORAGE
private static final int REQUEST_RUNTIME_PERMISSION = 123;
if (CheckPermission(youactivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
shareImageWhatsApp();
} else {
// you do not have permission go request runtime permissions
RequestPermission(AccesspointCheck.this, Manifest.permission.WRITE_EXTERNAL_STORAGE, REQUEST_RUNTIME_PERMISSION);
}
public void RequestPermission(Activity thisActivity, String Permission, int Code) {
if (ContextCompat.checkSelfPermission(thisActivity,
Permission)
!= PackageManager.PERMISSION_GRANTED) {
if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
Permission)) {
shareImageWhatsApp();
} else {
ActivityCompat.requestPermissions(thisActivity,
new String[]{Permission},
Code);
}
}
}
public boolean CheckPermission(Activity context, String Permission) {
if (ContextCompat.checkSelfPermission(context,
Permission) == PackageManager.PERMISSION_GRANTED) {
return true;
} else {
return false;
}
}
call shareImageWhatsApp in class
public void shareImageWhatsApp() {
Bitmap adv = BitmapFactory.decodeResource(getResources(), R.drawable.launcher_icon);
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/jpeg");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
adv.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
File f = new File(Environment.getExternalStorageDirectory()
+ File.separator + "temporary_file.jpg");
try {
f.createNewFile();
new FileOutputStream(f).write(bytes.toByteArray());
} catch (IOException e) {
e.printStackTrace();
}
share.putExtra(Intent.EXTRA_STREAM,
Uri.parse( Environment.getExternalStorageDirectory()+ File.separator+"temporary_file.jpg"));
if(isPackageInstalled("com.whatsapp",this)){
share.setPackage("com.whatsapp");
startActivity(Intent.createChooser(share, "Share Image"));
}else{
Toast.makeText(getApplicationContext(), "Please Install Whatsapp", Toast.LENGTH_LONG).show();
}
}
private boolean isPackageInstalled(String packagename, Context context) {
PackageManager pm = context.getPackageManager();
try {
pm.getPackageInfo(packagename, PackageManager.GET_ACTIVITIES);
return true;
} catch (PackageManager.NameNotFoundException e) {
return false;
}
}
