Android M权限对话框未显示 [英] Android M permission dialog not showing

问题描述

我目前正在尝试使我的应用程序适应Android M的新权限模型.

I'm currently trying to adapt my application to the new permissions model of Android M.

我正在收集我需要的所有权限，然后运行

I'm collecting all the permissions I require, then run

Log.i("Permissions", "Requesting permissions: " + permissions);
requestPermissions(requiredPermissions.toArray(new String[requiredPermissions.size()]), requestCodeForPermissions);

requiredPermissions拥有我需要的权限，例如android.permission.WRITE_EXTERNAL_STORAGE.

requiredPermissions holds the permissions I need like android.permission.WRITE_EXTERNAL_STORAGE.

该例程肯定已执行，因为我在logcat中有Log行:

That routine is definitely executed as I have the Log line in the logcat:

08-07 12:52:46.469: I/Permissions(1674): Requesting permissions: android.permission.RECEIVE_BOOT_COMPLETED; android.permission.WRITE_EXTERNAL_STORAGE

但是权限对话框从不显示，更不用说onRequestPermissionsResult()了.

But the permissions dialog never shows, let alone is onRequestPermissionsResult() called.

我做错了什么?根据一些教程，我发现我什么都没错过. 我只有用于测试的仿真器，没有物理设备.这是来自设置的关于"屏幕: 图像

What am I doing wrong? Based on some tutorials I found I'm not missing anything. I only have the emulator for testing, no physical device. This is the about screen from settings: Image

也许值得一提:如果我尝试从主屏幕打开已安装应用程序的概述，我只会得到launcher3 has exited.我不确定是否可能与此有关.

It might be worth mentioning something else: If I try to open the overview of installed apps from the home screen I only get launcher3 has exited. I'm not sure if that might be related.

有人知道为什么它不显示吗?

Does anybody have an idea why it's not showing?

推荐答案

基于Hilal的评论(非常感谢！): 就我而言，我的应用程序确实在使用tabhost，并且权限是从tabhost内的Activity请求的.在启动一个单独的活动并请求权限后，它就可以正常工作.

Based on the comment from Hilal (thanks a lot!): In my case my app is indeed using tabhost and the permissions were requested from an Activity inside the tabhost. After starting a separate activity that requests the permissions it is working.
