Ionic 应用程序未安装在 Android 设备中

Question

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.

Answer 1

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.

1. ionic cordova run android --device

2. Plugged device to the PC using USB

3. Copy the android-debug.apk file to the device (apk path:.. \\platforms\\android\\build\\outputs\\apk)

4. After that, You have to enable below setting on your Android device

settings --> general tab --> security --> unknown sources (enabled this)

5. 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.

Answer 2

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.

Answer 3

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.

Answer 4

Try building a signed apk.

First of all build a release apk using this.

ionic cordova build android --prod --release

Then run these commands in a command prompt. (Navigate to the folder where your apk is located)

keytool -genkey -v -keystore my-release-key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias my-alias

then,

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my-release-key.jks your_apk_name.apk my-alias

Answer 5

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