Ionic App not installing in android device

I am a newbie in Ionic. I just made a simple app in Ionic that ran well on browser. So, I converted it into an .apk file using Android studios that generated an android-release-unsigned.apk file. I transfered it to my device and on trying to install it I encountered that it was not being installed. I am not able to figure out the cause. Need some assistance.

You can follow the steps which are mentioned in the official doc below.
Deploying to a Device
But for me, it didn't work.So I just manually did that as shown below.
ionic cordova run android --device
Plugged device to the PC using USB
Copy the android-debug.apk file to the device (apk path:.. \platforms\android\build\outputs\apk)
After that, You have to enable below setting on your Android device
settings --> general tab --> security --> unknown sources (enabled this)
After that just double-clicked the android-debug.apk from the location which you have copied.Then your app will be installed on your device.That is it.You can use your app on real device now.

The most probable reason I can think of is that your application is not signed. As Sampath mentioned try to build a debug version and not release version of your application and then install it on your device. You can can use 'ionic run android' and copy/paste manually the output android-debug.apk file to your device.

In the config.xml, in the 2nd line, there is a tag called widget. You have to give a unique id for that. If there is another ionic app installed with same widget id, your device will not allow you to install another app with the same id.

$ adb devices
native-run android --app platform/your-app-debug-link.apk --device

nativescript livereload on device

i am using https://github.com/NathanWalker/angular2-seed-advanced which creates a running nativescript app.
now, i am a starter with nativescript and wanted to ask, how i can achieve a good development flow.
i am coming from ionic where i was able to see the console output on my development machine and was able to test my app live on a cable connected device. live reloading was running also.
so my questions:
can i run my app on a device without publishing it to the store
will i be able to see the console.log output somehow on my local dev machine with adb or a nativescript cli command?
is live reloading possible for developing nativescript apps?
Thank you in advance!

yes
yes
yes
tns livesync android --watch

You can install the app to your own Android / iOS real devices and/or the iOS simulator and Android emulators, all without sending it to any of the stores.
You can see the log fine, typically when you do a tns run [ios|android] the log is pipped back to your console. You can also run the standard adb logcat (android) or idevicesyslog (for iOS if installed)
Live reloading is possible, and works fairly well. You can use the tns run [android|ios] which is built into the tns command line.

The answer to all three questions is yes (as another answer point out). To add to answer of question 3,
As of nativescript version 2.5.0, tns run and tns livesync does the same thing, tns run has the ability to apply changes and sync it to a running app on device/emulator. The message on console clearly says tns livesync is being deprecated, so you should always look to use tns run

Here are the latest options(As of 2018-Jan) to run the app in live sync mode with a device when you are using NathanWalker -angular-seed-advanced.
iOS (device): npm run start.ios.device --debug
Android (device): npm run start.android.device --debug
--debug option will pull in more logs from the device(not just for your app, but also other activities)
Check the latest doc here for up-to date commands,
You can also use adb as explained here,

Ionic Build or Ionic Run builds the wrong app

I am trying to build or run an Ionic Cordova App. But it always builds a default app with playlists.
OS is Windows 10
I do the following from my command prompt:
c:\users\martijn\documents\ionic start testapp blank
c:\users\martijn\documents\testapp\ionic run android
now it is building a different app then in my app directory. When I do ionic serve I see the right app in my browser. Can't figure out why running or building gives me a different app, I think it is a default example app.
Can somebody help?

See link here:
https://github.com/driftyco/ionic-cli/issues/1283
Appears you may have to delete the the last apk file from platforms\android\build\outputs\apk

Build Phonegap 3.1 app locally for android

I started PhoneGap today only. I have experience with native code but not with HTML5 stuff. I am comfortable with GUI so CLI is new to me.
So I am trying to build app in android. But it uploads data to remote site & as its my second app, Its says "Private app limit reached".
Is there any way to build file locally?? Like with no internet connection. Screenshot attached for further refrence. Thankyou in advance

If you look at the Android platform guide section of the PhoneGap documentation you'll get instructions for setting up your SDK locally.
Pay attention so that you got your PATH setup correctly, a quick way to verify that on windows is to type echo %PATH% in the command prompt. If you already had your command prompt open as you set PATH it'll not be reflected so you've to close cmd and open it again.
After the SDK is setup successfully and you got your PATH verified you should be able to do the following to run it:
phonegap install android
phonegap local build android
phonegap local run android --emulator

Installing phonegap app to android emulator using windows CLI

I'm trying to install my Phonegap application onto an Android AVD/Emulator. I have launched the AVD and it's registering as 5554:Nexus_S.
When using the Phonegap commands at the Windows prompt I am typing:
phonegap build android
phonegap install android
The output I get says it successfully installed the app onto the device, but it never shows up. This is the output of the install command:
[phonegap] detecting Android SDK environment...
[phonegap] using the local environment
[phonegap] trying to install app onto device
cp: dest file already exists: C:\Users\username\app\platforms\android\assets\www\phonegap.js
[phonegap] successfully installed onto device
I've tried variations of targeting the device using options with no luck:
--device=5554
--target=5554
Any ideas?

I figured it out. You have to specify the --emulator= in the call, so the command looks like:
phonegap install --emulator=emulator-5554 android
You can find the name/id of your running emulators by running the list-started-emulators.bat under the /platforms/android/cordova/lib/ folder in your project.

Another quick note is that sometimes even when you have started the emulator phonegap will not recognize it... so you have to start it from phonegap bat file so that the right process number is registered. to do this.
Use the following command,
1. List-emulator-images.bat : This will display available emulator images you have
2. start-emulator : This will start the emulator which will register with phonegap.
Also make sure you are running all of this from and ADMIN Enabled command prompt.

Okay, I've solved my problem. This solution may not be applied to all, but I was suffering from the same problem as I've mentioned in the comments of the question.
What did I do wrong?
I made some changes in one of the plugins.
I was working on my app and added the Vibration plugin. I made some changes in the plugin, both in the generic version [your_project_root\plugins\org.apache.cordova.vibration\src\android\Vibration.java] and also in the platform specific version [your_project_root\platforms\android\src\org\apache\cordova\vibration\Vibration.java].
But when I reverted the changes back, everything went fine.
I say it again, this solution may not be generic but can be useful for at least my type of problem.
And this gives rise to another question, can't we make changes in the Plugins?I think it is totally fine to make changes in them. Maybe I had done something wrong.
