I am making an application to capture image once and then save it in SD card and display it on the application's MainActivity's ImageView(image_view)(which is handled in onRequestPermissionsResult() method). The application also helps to send email the picture clicked by user. Now for this I have requested 2 permssions:
1.) Camera Request
2.) External Storage Request
When the app launches the Camera Request dialog box appears but the External Storage Request Dialog box is not appearing and the app crashes displaying the toast as External write permissions has not been granted. Cannot Save File.
I have mentioned the requests in Manifest also
<uses-permission android:name="android.permissions.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.CAMERA" />
Code for requesting permissions
public void requestPermissions() {
if (ContextCompat.checkSelfPermission(this,
android.Manifest.permission.WRITE_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {
} else {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,android.Manifest.permission.WRITE_EXTERNAL_STORAGE)) {
Toast.makeText(this,
"External storage permission required to save images",
Toast.LENGTH_SHORT).show();
}
ActivityCompat.requestPermissions(this,new String[]{android.Manifest.permission.WRITE_EXTERNAL_STORAGE},
REQUEST_WRITE_EXTERNAL_STORAGE);
}
if (ContextCompat.checkSelfPermission(this,
android.Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED) {
launchCamera();
} else {
if (ActivityCompat.shouldShowRequestPermissionRationale(this,android.Manifest.permission.CAMERA)) {
Toast.makeText(this,
"External storage permission required to save images",
Toast.LENGTH_SHORT).show();
}
ActivityCompat.requestPermissions(this,new String[]{android.Manifest.permission.CAMERA},
REQUEST_CAMERA);
}
}
Here is the Full Code
public class MainActivity extends AppCompatActivity {
Button clickPhotoButton;
private static final String FILE_NAME="image01.jpg";
private static final int CAMERA_PIC_REQUEST = 100;

setContentView(R.layout.activity_main);
clickPhotoButton = (Button) findViewById(R.id.click_photo_button);
makeFolder();
}
public void makeFolder(){
if(!pictureDir.exists()) {
pictureDir.mkdirs();
}
Log.e("Prakhar", pictureDir.getAbsolutePath());
}
