Activity處理危險權限

//請求權限

String[] permissionArray = getPermission(new String[]{Manifest.permission.READ_CONTACTS,Manifest.permission.CALL_PHONE});
if(permissionArray.length>0){
    ActivityCompat.requestPermissions( this,permissionArray, REQUEST_CONTACTS );
}

//請求權限回饋

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if(requestCode == REQUEST_CONTACTS){
        if(grantResults.length>0){//取得權限成功
            
        }else{//取得權限失敗

        }
    }
}

//處理多個權限確認

private String[] getPermission(String[] permissionArray){
    ArrayList<String> requestPermissions = new ArrayList<>();
    for(String permission : permissionArray) {
        if(ActivityCompat.checkSelfPermission(this, permission) == PackageManager.PERMISSION_GRANTED){

        }else{
            requestPermissions.add(permission);
        }
    }
    return requestPermissions.toArray(new String[requestPermissions.size()]);;
}
