Android: instale .apk mediante programación [duplicado]
Hice esto con la ayuda de los problemas de descarga de archivos binarios de Android e instalé la aplicación mediante programación en Android .
Quiero realizar una actualización e instalación automáticas a la vez. Es local, por lo que no es una aplicación de mercado.
Aquí está mi código para ello:
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();
}
}
Mis permisos son INTERNET, WRITE_EXTERNAL_STORAGE, INSTALL_PACKAGESy DELETE_PACKAGES.
Cuando se carga Intent promptInstall, la aplicación falla =/
Entonces, ¿me faltan permisos o mi código es incorrecto o hay una mejor manera de hacerlo?
Aceptado
Resolví el problema. Cometí un error en setData(Uri)y 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);
Eso es correcto ahora, mi actualización automática está funcionando. Gracias por la ayuda. =)
Editar 20.7.2016:
Después de mucho tiempo, tuve que volver a utilizar esta forma de actualización en otro proyecto. Encontré una serie de problemas con la solución anterior. Muchas cosas han cambiado en ese tiempo, así que tuve que hacer esto con un enfoque diferente. Aquí está el código:
//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));
Para ICS, implementé su código e hice una clase que se extiende AsyncTask. ¡Espero que lo aprecies! Gracias por su código y solución.
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;
}
}
Para usarlo, en tu actividad principal llama de esta manera:
atualizaApp = new UpdateApp();
atualizaApp.setContext(getApplicationContext());
atualizaApp.execute("http://serverurl/appfile.apk");

Gracias por compartir esto. Lo tengo implementado y funcionando. Sin embargo:
1) Instalo la versión 1 de mi aplicación (funciona sin problemas)
2) Coloco la versión 2 en el servidor. la aplicación recupera la versión 2 y la guarda en la tarjeta SD y solicita al usuario que instale el nuevo paquete versión 2
3) la versión 2 se instala y funciona como se esperaba
4) El problema es que cada vez que se inicia la aplicación quiere que el usuario reinstale la versión 2 nuevamente.
Entonces estaba pensando que la solución era simplemente eliminar el APK en la tarjeta SD, pero la tarea asíncrona simplemente recuperará la versión 2 nuevamente para el servidor.
Entonces, la única forma de evitar intentar instalar nuevamente el apk v2 es eliminarlo de la tarjeta SD y del servidor remoto.
Como puedes imaginar, eso no va a funcionar realmente, ya que nunca sabré cuándo todos los usuarios recibieron la última versión.
Cualquier ayuda para resolver esto es muy apreciada.
IMPLEMENTÉ EL método "ldmuniz" mencionado anteriormente.
NUEVA EDICIÓN: Estaba pensando que todos mis APK tienen el mismo nombre. ¿Debería nombrar myapk_v1.0xx.apk y en esa versión configurar proactivamente la ruta remota para buscar v.2.0 cada vez que se lance?
Probé la teoría y RESUELVE el problema. Debe nombrar su archivo APK con algún tipo de versión, recordando siempre configurar su PRÓXIMO número de versión en su aplicación lanzada actualmente. No es ideal pero es funcional.
