I am trying to make a simple application in Java to install an APK on Android devices connected via USB. Using ABD manually or installing from Android Studio it works fine, but I wanted to give a simple single button click install option within my application, I have tried following code but unfortunately, it is not working
abdsourcesync = apkpath;
progress.setString("sync in progress");
System.out.println("Starting Sync via adb with command " + "adb"
+ " install -r " + apkpath);
Process process = Runtime.getRuntime().exec(
"adb" + " install -r " + apkpath);
InputStreamReader reader = new InputStreamReader(
process.getInputStream());
Scanner scanner = new Scanner(reader);
scanner.close();
int exitCode = process.waitFor();
System.out.println("Process returned: " + exitCode);
I have searched around here but I have only found installing an APK from within an Android application or from the android studio, not from a core Java. or java web module
Your helping hand would be really appreciated ;
You can Install Application from Java code using below way.
File outputFile = null;
try {
outputFile = new File(<APK Path>);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Uri apkUri = FileProvider.getUriForFile(mContext, BuildConfig.APPLICATION_ID + ".provider", outputFile);
Intent intent = new Intent(Intent.ACTION_INSTALL_PACKAGE);
intent.setData(apkUri);
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
mContext.startActivity(intent);
} else if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N){
Uri apkUri = Uri.fromFile(outputFile);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(apkUri, "application/vnd.android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
mContext.startActivity(intent);
}else {
Toast.makeText(mContext, "File not found.", Toast.LENGTH_LONG).show();
}
} catch (Exception e) {
e.printStackTrace();
}
Do not forget about runtime permissions
This simple example works for me for API 28. It opens an apk file to install from "Download folder"
For simplification: Download the apk file for application you want to install to "Download" folder of your phone. (There are a lot of instructions to do it programmaticaly, ot you can do it manualy)
