Question

我一直在 android studio 中开发一个简单的应用程序，但是当我尝试运行它时，我的应用程序不断崩溃。堆栈跟踪：

我不明白为什么会这样，我从不尝试在我的应用中使用麦克风或任何与音频相关的东西。

这是我的 AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.nick.project2" >

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme" >
    <activity android:name=".MainActivity" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

在调试我的 MainActivity.java 时，这是崩溃的代码块：

    public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    getFragmentManager().beginTransaction().add(R.id.professorContainer, myTeacher).commit();

    //Check to see if we should get the layout for a phone or a tablet
    if(findViewById(R.id.professorContainer) != null){
        //
        getFragmentManager().beginTransaction().add(R.id.professorContainer, myTeacher);
    }


}

它在 onCreate 方法的第三行崩溃，“getFragmentManager()....”

我猜你的布局中可能有一些快速搜索小部件。 Quicksearch 使用需要录音权限的谷歌语音识别 API。添加该权限。

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