这对我有用!!!在应用程序的您的启动活动中,执行以下操作,
This is worked for me !!! In Your Splash Activity of your application do the following,
注意::如果用户在一段时间后禁用该权限,则这些代码段将不允许进入应用程序而不会崩溃,它会要求一个对话框来允许该所需的权限.
Note: If user disables the permission after some time, these piece of code will not allow to get into the application without any crashes, it asks a dialog to allow that needed permission.
1)为请求代码声明一个int变量,
1) Declare an int variable for request code,
private static final int REQUEST_CODE_PERMISSION = 2;
2)声明一个具有所需权限名称的字符串,
2) Declare a string with the permissions name that you need,
String mPermission = Manifest.permission.ACCESS_FINE_LOCATION,
3)接下来,检查onCreate方法上运行时权限的条件,
3) Next Check the condition for runtime permission on your onCreate method,
try {
if (ActivityCompat.checkSelfPermission(this, mPermission)
!= MockPackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
mPermission, REQUEST_CODE_PERMISSION);
// If any permission above not allowed by user, this condition will execute every time, else your else part will work
}
} catch (Exception e) {
e.printStackTrace();
}
4)现在声明onRequestPermissionsResult方法以检查请求代码,
4) Now Declare onRequestPermissionsResult method to check the request code,
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
Log.e("Req Code", "" + requestCode);
if (requestCode == REQUEST_CODE_PERMISSION) {
if (grantResults.length == 1 &&
grantResults[0] == MockPackageManager.PERMISSION_GRANTED ) {
// Success Stuff here
}
else{
// Failure Stuff
}
}
}
