Question

我收到此错误，当我在设备上运行时，应用程序崩溃。

我使用的是Android Studio 1.3.2。

这是我的Stack Trace：

Answer 1

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

如果你想写一个联系人，也要写：

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

将这些行放入清单文件中（直接在“manifest”标记内）

Answer 2

在清单中添加权限

<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>

Android M +需要运行时权限implement like this code

Answer 3

如堆栈跟踪所示，您需要请求权限。 requires android.permission.READ_CONTACTS or android.permission.WRITE_CONTACTS

把它放在你的表现中

<uses-permission android:name="android.permission.READ_CONTACTS"/>
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>

请注意，如果您正在为Android M +构建，那么您还应该在运行时请求权限。

Android＆＃34;不幸的是，MyApp已停止＆＃34;
