首先考虑获得权限
然后在mainacitvity中获得动态权限
public static final int EXTERNAL_STORAGE_REQ_CODE = 10 ;
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); }}如果以上两种方法都不可以
在manifest的application中加入
android:requestLegacyExternalStorage=“true”
