안드로이드 스튜디오 : Permission 권한 넣기 / 권한이 맞으면 실행

내가 사용한 코드 이며 

카메라 , 내 위치, 내 저장소 등의 권한을 허용해주는 코드이다. 

코드를 통해서 권한을 허용시키며

권한이 허용 되었을때만 Intent를 할 수 있게 코드를 짰다.

 

 

버튼 클릭 시 Intent 할 수 있는 코드 

Button btn = findViewById(R.id.btn);
btn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

        if(ActivityCompat.checkSelfPermission(getApplicationContext(),Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED
                || ActivityCompat.checkSelfPermission(getApplicationContext(),Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
            Intent intent = new Intent(RequestActivity.this, MainActivity.class);
            startActivity(intent);
        }else {
            Toast.makeText(getApplicationContext(),"앱에 권한을 허용시켜 주세요 ",Toast.LENGTH_SHORT).show();
        }
    }
});

 

권한을 가져오는 코드 

public void OncheckPermission(){
            if(ActivityCompat.checkSelfPermission(this,Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
                || ActivityCompat.checkSelfPermission(this,Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED
                    || ActivityCompat.checkSelfPermission(this,Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED
                    || ActivityCompat.checkSelfPermission(this,Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED
                    || ActivityCompat.checkSelfPermission(this,Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED

            ){
                if(ActivityCompat.shouldShowRequestPermissionRationale(this,Manifest.permission.ACCESS_FINE_LOCATION)){
                    Toast.makeText(this,"앱 실행을 위해서는 권한을 설정해야 합니다",Toast.LENGTH_SHORT).show();
                    ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.ACCESS_COARSE_LOCATION
                            ,Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.CAMERA},
                            PERMISSIONS_REQUEST);

                }else {
                    ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.ACCESS_FINE_LOCATION,Manifest.permission.ACCESS_COARSE_LOCATION
                                    ,Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.CAMERA},
                            PERMISSIONS_REQUEST);
                }
            }
        }

    @Override
    public void onRequestPermissionsResult(int requestCode,@NonNull String permissions[],@NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        switch (requestCode) {
            case PERMISSIONS_REQUEST:
                if (grantResults.length>0
                    && grantResults[0] == PackageManager.PERMISSION_GRANTED){
                Toast.makeText(this, "앱 실행을 위한 권한이 설정되었습니다", Toast.LENGTH_SHORT).show();
            }else{
                Toast.makeText(this, "앱 실행을 위한 권한이 취소 되었습니다", Toast.LENGTH_SHORT).show();

            }
            break;
        }
    }
}
