My suggestion is to use plugin mechanism instad of updating the app. You can dynamically load classes from the Web and run them inside your app without any user interaction. There is a lot of resources spread across the Internet:

Solved it! :D

It just works in rooted devices but works perfectly.
Using the unix cmd "pm" (packageManager) allows you to install apks from sdcard, when executing it as root.

Hope this could help some people in the future. 

<pre><code>public static void installNewApk()
{
 try
 {
 Runtime.getRuntime().exec(new String[] {"su", "-c", "pm install -r /mnt/internal/Download/fp.apk"});
 }
 catch (IOException e)
 {
 System.out.println(e.toString());
 System.out.println("no root");
 }
}
</code></pre>

Required permissions:

<pre><code>&lt;uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /&gt;
&lt;uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /&gt;
</code></pre>

If <code>su -c</code> doesn't work, try <code>su 0</code> (only rooted devices can do su!)

The full answer looks like this:

<pre><code>private void installNewApk()
 {
 String path = mContext.getFilesDir().getAbsolutePath() + "/" + LOCAL_FILENAME;
 mQuickLog.logD("Install at: " + path);
 ProcessUtils.runProcessNoException(mQuickLog, "su", "0", "pm", "install", "-r", path);
 }
</code></pre>

With this class defined:

<pre><code>public class ProcessUtils {
 Process process;
 int errCode;
 public ProcessUtils(String ...command) throws IOException, InterruptedException{
 ProcessBuilder pb = new ProcessBuilder(command);
 this.process = pb.start();
 this.errCode = this.process.waitFor();
 }

 public int getErrCode() {
 return errCode;
 }

 public String getOutput() throws IOException {
 InputStream inputStream = process.getInputStream();
 InputStream errStream = process.getErrorStream();
 BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));
 String line;
 StringBuilder sb = new StringBuilder();
 while ((line = br.readLine()) != null) {
 sb.append(line + System.getProperty("line.separator"));
 }

 br = new BufferedReader(new InputStreamReader(errStream));
 while ((line = br.readLine()) != null) {
 sb.append(line + System.getProperty("line.separator"));
 }
 return sb.toString();
 }


 public static String runProcess(String ...command) throws IOException, InterruptedException {
 ProcessUtils p = new ProcessUtils(command);
 if (p.getErrCode() != 0) {
 // err
 }
 return p.getOutput();
 }

 public static void runProcessNoException(String ...command) {
 try {
 runProcess(command);
 } catch (InterruptedException | IOException e) {
 // err
 }
 }
}
</code></pre>

TL:DR; version ;)

<ul>
<li>my app should run without user interaction (autostart etc works)</li>
<li>it should update itself (via apk) without any user interaction</li>
<li>rooted devices are possible</li>
</ul>

.

problem:

<ul>
<li>querying a newer apk from a server works</li>
<li>when starting the apk with a (view?) intent, the "install app" prompt pops and needs a user confirmation</li>
</ul>

How do I solve this without any user interaction?

This seems to be a solution, but there must be better approach.

I already found this: <a href="https://stackoverflow.com/questions/4604239/install-application-programmatically-on-android">Install Application programmatically on Android</a>

but that doesn't solve my problem.

Self updating app
