Answer 1

请查看此Google指南：Demo page

基本上，您需要的只是清单中的此权限：

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

Answer 2

您也可以在运行时请求权限，因此定义权限也是必要的。您可以通过以下方式申请Runtime Permisison。

// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
                Manifest.permission.READ_CONTACTS)
        != PackageManager.PERMISSION_GRANTED) {

    // Should we show an explanation?
    if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
            Manifest.permission.READ_CONTACTS)) {

        // Show an explanation to the user *asynchronously* -- don't block
        // this thread waiting for the user's response! After the user
        // sees the explanation, try again to request the permission.

    } else {

        // No explanation needed, we can request the permission.

        ActivityCompat.requestPermissions(thisActivity,
                new String[]{Manifest.permission.READ_CONTACTS},
                MY_PERMISSIONS_REQUEST_READ_CONTACTS);

        // MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
        // app-defined int constant. The callback method gets the
        // result of the request.
    }
}

For 5.1.1 you need to just Add permission to manifest xml

<manifest>

     //For Write to External storage
     <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

     //For Read from External storage
     <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

           ...
     <application>
            ...
            <activity> 
                ...
            </activity>
     </application>
</manifest>

But later than 6.0 you need to add permission runtime too.
