Contents in this project Requesting Runtime Permission in Android Marshmallow 6.0 :
- Watch the live demo video.
- Start a new application development project in Android Studio.
- Add permission in Manifest.xml file.
- Create a button in activity layout file.
- Declare button object and assign button ID in MainActivity.java .
- Create method to implement Runtime Permission.
- Set setOnClickListener() on button.
- Call Runtime method inside button click scope.
1. Watch the live demo video :
2. Start a new application development project in Android Studio.
After seeing the live demo video we could actually know how the Runtime Permission works in android apps.
3. Add permission in Manifest.xml file.
Next rule is to add permission in your Manifest.xml file we would add READ_EXTERNAL_STORAGE permission. This is used to give the privilege of application so app can access the memory card or storage of your device.
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
4. Create a button in activity layout file.
<Button
android:text="Enable RunTime Permission"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
android:id="@+id/button" />
5. Declare button object and assign button ID in MainActivity.java .
Button button ; button = (Button)findViewById(R.id.button);
6. Create method to implement Runtime Permission..
public void AllowRunTimePermission(){
if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE))
{
Toast.makeText(MainActivity.this,"READ_EXTERNAL_STORAGE permission Access Dialog", Toast.LENGTH_LONG).show();
} else {
ActivityCompat.requestPermissions(MainActivity.this,new String[]{ Manifest.permission.READ_EXTERNAL_STORAGE}, 1);
}
}
@Override
public void onRequestPermissionsResult(int RC, String per[], int[] Result) {
switch (RC) {
case 1:
if (Result.length > 0 && Result[0] == PackageManager.PERMISSION_GRANTED) {
Toast.makeText(MainActivity.this,"Permission Granted", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(MainActivity.this,"Permission Canceled", Toast.LENGTH_LONG).show();
}
break;
}
}
7. Set setOnClickListener() on button.
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
}
});
8. Call Runtime method inside button click scope.
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
AllowRunTimePermission();
}
});
