failed to parse package

[leoalemao3]

good night friend, please help me, I've been using your plugin for some time, I have many cases that after the end of the download I get "failed to parse package" and it doesn't install, if I try a few times (2,3) I can do the successful installation. sorry about my English

My first assumption would be: there is something wrong with the APK itself.
Maybe the signature was changed in the APK. Maybe corrupted.

Can you install the APK without the plugin?
If so, I need some details.

• Plugin version
• Android version
• Is the APK zipped?

The easiest way to debug it is to connect the device to the PC and read the logcat.
Either via Android Studio or via the command: adb logcat.

Thank you very much for the brief feedback, If I install the apk manually (without using the plug) I always have success. I'm splitting the apk into 1 mb loss, total 18 loss with the manifest. Again I say that in a few attempts without any change in the code I get success using the plug, I'll leave a piece of my code below.

plugin version: cordova-plugin-apkupdater 1.2.3 "Apk Updater"

Android version:8.1.0

ionic v3
Angular CLI: 8.0.2

cordova.plugins.apkupdater.setObserver(

this.downloadProgressAPK = nPercentage

      console.log('Download: ' + nPercentage + ' (' + nChunksWritten + '/' + nChunks + ')');

      this.downloadProgressAPK = nPercentage;

    this.downloadProgressAPK = "Progresso do Download" + " " + parseInt(this.downloadProgressAPK) + "%";


      document.getElementById('download').innerText = this.downloadProgressAPK ;

    },
    unzipProgress: function (nPercentage) {
  
        console.log('Unzipping: ' + nPercentage);
    },

I would recommend you to migrate to the new plugin version (> 2.0.0). This version is much better designed and less buggy.

[leoalemao3]

Thank you very much for the feedback !!

I updated the plug it was show, very good to be able to put the entire apk on the server.

I'm going to test now I believe the error will be corrected, I have a question, is it possible to install the apk without user intervention?

[kolbasa]

If the device is rooted, then there is this option. This will install the update and also restart the app afterwards.
All without the app user's intervention.

await ApkUpdater.rootInstall();

There is a second way. If the app is registered as Device Admin, then this would work even without root.
However, I have not yet implemented a method for this. But that is planned soon.

thank you very much for the feedback but my device is not rooted
