Question

我正在试图给一个Android应用WRITE_EXTERNAL_STORAGE，但它似乎没有在模拟器中获得权限。 Android.manifest如下所示：

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

如你所见，我清楚android.permission.WRITE_EXTERNAL_STORAGE。任何人都知道为什么还没有给出许可？我尝试了各种模拟器（API 24,26,28）。

任何想法都赞赏。

Answer 1

我已用PermissionsAndroid.request(PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE)修复了它。

Answer 2

您是否尝试过设置：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="28" tools:replace="android:maxSdkVersion" />

取自： WRITE_EXTERNAL_STORAGE not working on lollipop even though it's set in the manifest

甚至是这样：

 <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" tools:node="replace" />

Appranetly SDK＆gt;即使某些事情被指定，23也需要获得许可。

https://developer.android.com/training/permissions/requesting

private static final int PERMISSION_WRITE_REQUEST_CODE = 1;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {

    if (checkSelfPermission(Manifest.permission.WRITE_EXTERNAL_STORAGE)
            == PackageManager.PERMISSION_DENIED) {

        Log.d("WritePermission", "No write permission given. Requesting...");
         ActivityCompat.requestPermissions(thisActivity,
                new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
                PERMISSION_WRITE_REQUEST_CODE);
    }
}

没有给出存储许可
