Android Studio 中的 Android Emulator 不显示我的应用

Question

I'm currently working on an android application using Android Studio. When I run my code on a Nexus 5 API 21 x86 emulator, the emulator does not show the application that I am trying to debug. I went into all applications, but I still cannot find the app I am trying to test. However, the emulator does still show an app from a previous project that I was working on. The log doesn't show any errors either when compiling the gradle and starting up the emulator.

From researching other posts, I believe it may have something to do with the version of the emulator I am running. I am not sure if that is the case and if it is how I would fix it. I have pasted a copy of my manifest below and my gradle.build. Please let me know what is wrong, this problem has been irritating me for the last several days.

 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.jamescho.androidgame"
    android:versionCode="1"
    android:versionName="0.5" >

    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

    <application
        android:icon="@drawable/bxbx_char"
        android:label="Bxbx">
        <activity
            android:name="com.Bxbx.BxbxGame.Game"
            android:configChanges="keyboard|keyboardHidden|orientation"
            android:label="Bxbx"
            android:screenOrientation="portrait">
             <intent-filter>
                 <action android:name="android.intent.action.MAIN"/>
                 <category android:name="android.intent.category.LAUNCHER"/>
             </intent-filter>
        </activity>
    </application>

</manifest>

And the build.gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 17
    buildToolsVersion "19.1.0"

    defaultConfig {
        applicationId "com.jamescho.androidgame"
        minSdkVersion 8
        targetSdkVersion 17
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:support-v4:18.+'

Answer 1

From Android Studio, go to the AVD manager (Tools>Android>AVD). Locate your virtual device, and then under actions, select the downward triangle and hit Wipe Data. This should remove the old test APK.

If the old app is still there, try just deleting the old virtual device and creating a new one. If it is still there, you are probably selecting the wrong virtual device when starting your app.

You should also try clearing the default testing device. Under Run>Edit Configurations, select the default run configuration. On the General tab, go to the bottom under Deployment Target Options and select Open Select Target Deployment Dialog, then save and try again.
