Ionic Application won't run on android

Question

I have an ionic application that I try to run on the android platform. When I execute

ionic run android

Or

ionic emulate android

I have the following message:

Total time: 0.814 secs Built the following apk(s): /Volumes/DATA/apps/my_app/platforms/android/build/outputs/apk/android-debug.apk ANDROID_HOME=/usr/local/Cellar/android-sdk/24.4.1_1 JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_101.jdk/Contents/Home

The application won't launch.

Here is the result of the ionic info command:

Cordova CLI: 6.4.0 
Ionic CLI Version: 2.1.14
Ionic App Lib Version: 2.1.7
ios-deploy version: 1.7.0 
ios-sim version: 3.1.1 
OS: OS X Yosemite
Node Version: v4.4.5
Xcode version: Xcode 6.3 Build version 6D570

Thanks in advance.

Answer 1

Try remove android platform and reinstall :

ionic platform rm android
ionic platform add android

Answer 2

After adding the platform, just go to this path file: platforms/android/cordova/lib/device.js

Comment this uninstall function line by changing this:

.return Adb.uninstall(resolvedTarget.target, pkgName)
    .then(function() {
        return Adb.install(resolvedTarget.target, apk_path, {replace: true});
});

to this:

//.return Adb.uninstall(resolvedTarget.target, pkgName)
//    .then(function() {
//         return Adb.install(resolvedTarget.target, apk_path, {replace: true});
//    });
