First look at the effect:

1. While I was using ecslipse, I've been working on the issue of "Android Studio installs multiple identical apk on the same phone", but not every time. One of the stupidest ways is to change the package name of the project. But obviously this is a dubious thing. Starting with Android Studio last year, I finally found out how to install the same apk on one phone. This also thanks gradle-plugin this plugin, is very powerful, nonsense not much to say directly on the code:
Here's a build of mine

Apply plugin:' Com.android.application 'Android {Compilesdkversion ABuildtoolsversion"22.0.1"Defaultconfig {ApplicationID"Com.guoyoujin.gz.gz"Minsdkversion -Targetsdkversion AVersioncode1Versionname"1.0"} buildtypes {debug {Applicationidsuffix"Debug"} release {minifyenabledfalseProguardfiles Getdefaultproguardfile (' Proguard-android.txt '),' Proguard-rules.pro '}}}repositories {maven {URL"https://oss.sonatype.org/content/repositories/snapshots/"}}dependencies {Compile Filetree (include: [' *.jar '], dir:' Libs ') Compile' com.android.support:appcompat-v7:22.2.0 'Compile' com.android.support:support-v4:22.2.0 'Compile' com.nineoldandroids:library:2.4.0 'Compile' com.ogaclejapan.smarttablayout:library:[email protected] 'Compile' com.ogaclejapan.smarttablayout:utils-v4:[email protected] 'Compile' com.android.support:recyclerview-v7:22.2.0 'Compile' com.android.support:support-v13:22.2.0 'Compile' com.google.code.gson:gson:2.2.4 'Compile' com.facebook.fresco:fresco:0.5.0 'Compile' com.orhanobut:logger:1.10 'Compile' org.lucasr.twowayview:core:[email protected] 'Compile' org.lucasr.twowayview:layouts:[email protected] 'CompileFiles(' Libs/universal-image-loader-1.9.1-with-sources.jar ') CompileFiles(' Libs/com.hck.book.jar ') CompileFiles(' Libs/msc.jar ') CompileFiles(' Libs/pinyin4j-2.5.0.jar ')}

Here's the point:

 buildTypes {        debug {            "debug"        }        release {            false            proguardFiles getDefaultProguardFile(‘proguard-android.txt‘‘proguard-rules.pro‘        }    }

This debug applicationidsuffix can be easily changed to generate the test apk you want to ApplicationID, understand the Android must know what the concept of
This means that you can install a different app at will. This is how good, you do not have to fear can not give the test personnel to install a number of APK, these apk can be used normally, to show you the effect, see below I have installed several:
