android6.0 存储权限 android设置存储权限

Activity中校验权限即可。

首先在manifest中加上SD卡权限

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />

Activity 中添加权限校验

private static final int REQUEST_EXTERNAL_STORAGE = 1;
    private static String[] PERMISSIONS_STORAGE = {
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.WRITE_EXTERNAL_STORAGE,
            Manifest.permission.MOUNT_UNMOUNT_FILESYSTEMS};

    public static void verifyStoragePermissions(Activity activity) {
        int permission = ActivityCompat.checkSelfPermission(activity,
                Manifest.permission.ACCESS_FINE_LOCATION);

        if (permission != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(activity, PERMISSIONS_STORAGE,
                    REQUEST_EXTERNAL_STORAGE);
        }
    }

onCreate中调用

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        verifyStoragePermissions(this);
        ...
    }
