#這個,是我第一次寫個個人心得的博客吧
我在程序員的道路上,一步一個腳印吧
Android 開發中,在自己做的音樂播放器中,一個權限的問題,讓我糾結了好幾天,今天終於解開了。國內網站,確實搜不出什麼有用的。
Android API 23以上,對權限的使用,不光是在Mainfeast中了,需要在運行的代碼塊中加入
具體代碼:
代碼塊
代碼塊語法遵循標準markdown代碼,例如:
// Storage Permissions
private static final int REQUEST_EXTERNAL_STORAGE = 1;
private static String[] PERMISSIONS_STORAGE = {
Manifest.permission.READ_EXTERNAL_STORAGE,
Manifest.permission.WRITE_EXTERNAL_STORAGE
};
/**
* Checks if the app has permission to write to device storage
*
* If the app does not has permission then the user will be prompted to grant permissions
*
* @param activity
*/
public static void verifyStoragePermissions(Activity activity) {
// Check if we have write permission
int permission = ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);
if (permission != PackageManager.PERMISSION_GRANTED) {
// We don't have permission so prompt the user
ActivityCompat.requestPermissions(
activity,
PERMISSIONS_STORAGE,
REQUEST_EXTERNAL_STORAGE
);
}
}
