Android: installer .apk par programme
Je l'ai fait avec l'aide de problèmes de fichiers binaires Android à télécharger et Installer l'application par programme sur Android .
Je veux faire la mise à jour automatique et l'installation automatique à la fois. C'est local, donc c'est une application non marchande.
Voici mon code pour cela:
public void Update(String apkurl){
try {
URL url = new URL(apkurl);
HttpURLConnection c = (HttpURLConnection) url.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
String PATH = Environment.getExternalStorageDirectory() + "/download/";
File file = new File(PATH);
file.mkdirs();
File outputFile = new File(file, "app.apk");
FileOutputStream fos = new FileOutputStream(outputFile);
InputStream is = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = is.read(buffer)) != -1) {
fos.write(buffer, 0, len1);
}
fos.close();
is.close();//till here, it works fine - .apk is download to my sdcard in download file
Intent promptInstall = new Intent(Intent.ACTION_VIEW)
.setData(Uri.parse(PATH+"app.apk"))
.setType("application/Android.com.app");
startActivity(promptInstall);//installation is not working
} catch (IOException e) {
Toast.makeText(getApplicationContext(), "Update error!", Toast.LENGTH_LONG).show();
}
}
Mes autorisations sont INTERNET, WRITE_EXTERNAL_STORAGE, INSTALL_PACKAGES et DELETE_PACKAGES.
Lorsque l'intention promptInstall est chargée, l'application se bloque = /
Alors, est-ce que je manque d'autorisations ou mon code est incorrect, ou existe-t-il un meilleur moyen de le faire?
J'ai résolu le problème. J'ai fait une erreur dans setData(Uri) et setType(String).
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(Environment.getExternalStorageDirectory() + "/download/" + "app.apk")), "application/vnd.Android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
C'est correct maintenant, ma mise à jour automatique fonctionne. Merci pour l'aide. =)
Edit 20.7.2016:
Après un long moment, j'ai dû utiliser cette méthode de mise à jour dans un autre projet. J'ai rencontré un certain nombre de problèmes avec l'ancienne solution. Beaucoup de choses ont changé au cours de cette période et j'ai donc dû adopter une approche différente. Voici le code:
//get destination to update file and set Uri
//TODO: First I wanted to store my update .apk file on internal storage for my app but apparently Android does not allow you to open and install
//aplication with existing package from there. So for me, alternative solution is Download directory in external storage. If there is better
//solution, please inform us in comment
String destination = Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "/";
String fileName = "AppName.apk";
destination += fileName;
final Uri uri = Uri.parse("file://" + destination);
//Delete update file if exists
File file = new File(destination);
if (file.exists())
//file.delete() - test this, I think sometimes it doesnt work
file.delete();
//get url of app on server
String url = Main.this.getString(R.string.update_app_url);
//set downloadmanager
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
request.setDescription(Main.this.getString(R.string.notification_description));
request.setTitle(Main.this.getString(R.string.app_name));
//set destination
request.setDestinationUri(uri);
// get download service and enqueue file
final DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
final long downloadId = manager.enqueue(request);
//set BroadcastReceiver to install app when .apk is downloaded
BroadcastReceiver onComplete = new BroadcastReceiver() {
public void onReceive(Context ctxt, Intent intent) {
Intent install = new Intent(Intent.ACTION_VIEW);
install.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
install.setDataAndType(uri,
manager.getMimeTypeForDownloadedFile(downloadId));
startActivity(install);
unregisterReceiver(this);
finish();
}
};
//register receiver for when .apk download is compete
registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));
Pour ICS, j'ai implémenté votre code et créé une classe qui étend AsyncTask. J'espère que vous l'appréciez! Merci pour votre code et votre solution.
public class UpdateApp extends AsyncTask<String,Void,Void>{
private Context context;
public void setContext(Context contextf){
context = contextf;
}
@Override
protected Void doInBackground(String... arg0) {
try {
URL url = new URL(arg0[0]);
HttpURLConnection c = (HttpURLConnection) url.openConnection();
c.setRequestMethod("GET");
c.setDoOutput(true);
c.connect();
String PATH = "/mnt/sdcard/Download/";
File file = new File(PATH);
file.mkdirs();
File outputFile = new File(file, "update.apk");
if(outputFile.exists()){
outputFile.delete();
}
FileOutputStream fos = new FileOutputStream(outputFile);
InputStream is = c.getInputStream();
byte[] buffer = new byte[1024];
int len1 = 0;
while ((len1 = is.read(buffer)) != -1) {
fos.write(buffer, 0, len1);
}
fos.close();
is.close();
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File("/mnt/sdcard/Download/update.apk")), "application/vnd.Android.package-archive");
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // without this flag Android returned a intent error!
context.startActivity(intent);
} catch (Exception e) {
Log.e("UpdateAPP", "Update error! " + e.getMessage());
}
return null;
}
}
Pour l'utiliser, appelez votre activité principale de la manière suivante:
atualizaApp = new UpdateApp();
atualizaApp.setContext(getApplicationContext());
atualizaApp.execute("http://serverurl/appfile.apk");
Cette question est très utile MAIS N'oubliez pas de monter la carte SD dans votre émulateur, si vous ne le faites pas, cela ne fonctionnera pas.
Je perds mon temps avant de découvrir cela.

Merci de partager cela. Je l'ai mis en œuvre et fonctionne. Pourtant:
1) J'installe la version 1 de mon application (aucun problème) 2) Je place la version 2 sur le serveur. l'application récupère ver2 et l'enregistre sur la carte SD et invite l'utilisateur à installer le nouveau package ver2 3) ver2 s'installe et fonctionne comme prévu 4) Le problème est que, chaque fois que l'application démarre, elle demande à l'utilisateur de réinstaller la version 2.
Je pensais donc que la solution consistait simplement à supprimer l'APK sur la carte SD, mais la tâche asynchrone récupèrerait simplement ver2 à nouveau pour le serveur.
Donc, le seul moyen d'arrêter d'essayer d'installer à nouveau l'apk v2 est de supprimer de sdcard et du serveur distant.
Comme vous pouvez l’imaginer, cela ne fonctionnera pas vraiment car je ne saurai jamais quand tous les utilisateurs auront reçu la dernière version.
Toute aide pour résoudre ce problème est grandement appréciée.
J'ai mis en œuvre la méthode "ldmuniz" indiquée ci-dessus.
NEW EDIT: Je pensais juste que tous les APK de moi portent le même nom. Devrais-je nommer myapk_v1.0xx.apk et, et dans cette version, définir de manière proactive le chemin distant pour rechercher la v.2.0 chaque fois qu'elle est publiée?
J'ai testé la théorie et cela résout le problème. Vous devez nommer votre fichier APK comme une sorte de contrôle de version, en vous rappelant de toujours définir votre numéro de version NEXT dans votre application actuellement publiée. Pas idéal mais fonctionnel.
