Question

我尝试在模拟器上运行我的应用程序，并在设置断点时收到以下错误消息：

Exception is equal to  {ErrnoException@3591} 
       errno is equal to 2
   functionName is equal to {String@3602} "stat"
cause is equal to  {ErrnoException@3591} "android.system.ErrnoException: stat failed: ENOENT (No such file or directory)"

我的清单代码

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="divya.love.prasanth.bow" >

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

<application
android:allowBackup="true"

android:theme="@style/AppTheme"

    android:value="AIzaSyCNCJ2SVopyUeCZosW7xtT-464MT-QA-rA  "/>

<activity
    android:name=".MainActivity"
    android:label="@string/app_name" >
</activity>

<activity android:name=".DispatchActivity"
    android:label="BOW">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

<activity android:name=".LoginActivity" />
<activity android:name=".SignUpActivity" />
<activity android:name=".SignUpOrLoginActivity" />
</application>

</manifest>

这是我的logcat

有人可以告诉我发生了什么以及如何解决这个问题吗？

Answer 1

我认为您的活动会扩展导致问题的ActionBarActivity，尝试替换此代码，

<activity
android:name=".MainActivity"
android:label="@string/app_name" >

in Manifest with，

<activity
android:name=".MainActivity"
android:theme="@style/Theme.AppCompat"
android:label="@string/app_name" >

Android应用程序意外停止在模拟器中
