Android Request Multiple Permissions at RunTime

Runtime Permissions

App users grant permissions to apps while the app is running, not when they install the app. This approach streamlines the app install process, since the user does not need to grant permissions when they install or update the app. It also gives the user more control over the app’s functionality; for example, a user could choose to give a camera app access to the camera but not to the device location. The user can revoke the permissions at any time, by going to the app’s Settings screen.

Step by Step Tutorial

Step 1: Open Android Studio.

Step 2: Create a new project as follows:

If you see the Welcome to Android Studio dialog, choose Start a new Android Studio project, available under ‘Quick Start’ on the right of the dialog.
Otherwise, click File in the Android Studio menu bar, then New, New Project.
Step 3: Enter your app name, company domain, and project location, as prompted. Then click Next.

Step 4: Select the form factors you need for your app. If you’re not sure what you need, just select Phone and Tablet. Then click Next.

Step 5: Select Blank Activity in the ‘Add an activity to Mobile’ dialog. Then click Next.

Step 6: Enter the activity name, layout name and title as prompted. The default values are fine. Then click Finish.

After that wait for few seconds. Android Studio starts Gradle and builds of your project.

Step 7: First of all adding permission in Android Manifest xml file.

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.MEDIA_CONTENT_CONTROL"/>
<uses-permission android:name="android.permission.CAMERA"/>

Step 8: Now go to MainActivity.xml file and create a new boolean method.

public static boolean hasPermissions(Context context, String... permissions){

    if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.M && context!=null && permissions!=null){
        for(String permission: permissions){
            if(ActivityCompat.checkSelfPermission(context, permission)!=PackageManager.PERMISSION_GRANTED){
                return  false;
            }
        }
    }
    return true;
}

Step 9: Now add below mentioned lines on onCreate() method.

int Permission_All = 1;

String[] Permissions = {Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.MEDIA_CONTENT_CONTROL, Manifest.permission.CAMERA, };
if(!hasPermissions(this, Permissions)){
    ActivityCompat.requestPermissions(this, Permissions, Permission_All);
}

Now your project is ready to run.
