#Perm for Android#
Perm is a library that makes it simple to check and request Android Permissions at runtime (like Camera or GPS) for Apps targetting Android 6 or more.
To Check and Request a permission, simply create a Perm instance, and use isGranted, isDenied or askPermission methods:
public class MainActivity extends AppCompatActivity {
private static final int PERMISSION_CAMERA_REQUEST = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
Perm cameraPermission = new Perm(this, Manifest.permission.CAMERA);
if (cameraPermission.isGranted()) {
Toast.makeText(this, "Camera Permission already granted", Toast.LENGTH_LONG).show();
} else if (cameraPermission.isDenied()) {
Toast.makeText(this, "Camera Permission already denied", Toast.LENGTH_LONG).show();
} else {
cameraPermission.askPermission(PERMISSION_CAMERA_REQUEST);
}
}
}To handle the result of the request, create a PermResult in the onRequestPermissionsResult of your Activity, and use isGranted, or isDenied methods.
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
if (requestCode == PERMISSION_CAMERA_REQUEST) {
PermResult cameraPermissionResult = new PermResult(permissions, grantResults);
if (cameraPermissionResult.isGranted()) {
Toast.makeText(this, "Camera Permission granted", Toast.LENGTH_LONG).show();
} else if (cameraPermissionResult.isDenied()) {
Toast.makeText(this, "Camera Permission denied", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(this, "Camera Permission cancelled", Toast.LENGTH_LONG).show();
}
}
}Don't forget to add the required permissions in your AndroidManifest.xml file! For example
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.mycompany.myapp">
<uses-permission
android:name="android.permission.CAMERA"
android:required="false" />
...Add the following maven{} line to your PROJECT build.gradle file
allprojects {
repositories {
jcenter()
maven { url "https://jitpack.io" } // add this line
}
}
Add the libary dependency to your APP build.gradle file
dependencies {
compile 'com.github.smart-fun:Perm:1.0.0' // add this line
}
