Android: .apk를 프로그래밍 방식으로 설치
안드로이드 다운로드 이진 파일 문제와 안드로이드에 프로그래밍 방식으로 응용 프로그램 설치의 도움을 받아 만들었습니다.
한 번에 자동 업데이트와 자동 설치를 하고 싶습니다.로컬이므로 비시장 응용 프로그램입니다.
제 코드는 다음과 같습니다.
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();
}
}
내 권한은 다음과 같습니다.INTERNET,WRITE_EXTERNAL_STORAGE,INSTALL_PACKAGES,그리고.DELETE_PACKAGES.
의도된 경우promptInstall로드되면 앱이 충돌합니다. =/
사용 권한이 누락되었거나 코드가 잘못되었거나 이를 위한 더 나은 방법이 있습니까?
저는 그 문제를 해결했습니다.제가 실수했습니다.setData(Uri)그리고.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);
맞습니다, 자동 업데이트가 작동합니다.도와주셔서 감사합니다. =)
2016년 7월 20일 편집:
오랜 시간이 지난 후, 저는 다른 프로젝트에서 이 업데이트 방법을 다시 사용해야 했습니다.이전 솔루션과 관련하여 여러 가지 문제가 발생했습니다.그 시간 동안 많은 것들이 바뀌었기 때문에, 저는 다른 접근법으로 이것을 해야 했습니다.코드는 다음과 같습니다.
//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));
ICS를 위해 당신의 코드를 구현하고 확장하는 클래스를 만들었습니다.AsyncTask감사합니다!당신의 코드와 솔루션에 감사드립니다.
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;
}
}
이 기능을 사용하려면 다음 방법으로 주요 활동 전화를 걸어야 합니다.
atualizaApp = new UpdateApp();
atualizaApp.setContext(getApplicationContext());
atualizaApp.execute("http://serverurl/appfile.apk");

공유해 주셔서 감사합니다.저는 그것을 구현하고 작동시킵니다.그러나:
나는 내 앱의 ver 1을 설치합니다 (문제없이 작동합니다)
나는 서버에 ver 2를 배치합니다.앱이 ver2를 검색하여 SD 카드에 저장하고 사용자에게 새 패키지 ver2를 설치하라는 메시지를 표시합니다.
ver2가 설치되어 예상대로 작동합니다.
문제는 앱이 시작될 때마다 사용자가 버전 2를 다시 설치하기를 원한다는 것입니다.
그래서 나는 해결책이 단순히 sdcard의 APK를 삭제하는 것이라고 생각했지만, 비동기 작업은 서버에 대해 ver2를 다시 검색할 것입니다.
따라서 v2 apk를 다시 설치하는 것을 막는 유일한 방법은 sdcard와 원격 서버에서 제거하는 것입니다.
모든 사용자가 최신 버전을 언제 받았는지 알 수 없기 때문에, 당신이 상상할 수 있듯이, 그것은 실제로 작동하지 않을 것입니다.
이 문제를 해결하는 데 도움이 된다면 대단히 감사하겠습니다.
저는 위에 나열된 "ldmuniz" 방법을 구현했습니다.
새로운 편집: 저는 APK의 이름이 모두 같다고 생각하고 있었습니다.myapk_v1.0xx.apk의 이름을 지정하고 v.2.0이 릴리스될 때마다 원격 경로를 사전에 검색하도록 설정해야 합니까?
저는 그 이론을 테스트했고 그것이 문제를 해결해줍니다.APK 파일의 이름을 어떤 버전으로 지정해야 하며, 현재 출시된 앱에서 항상 다음 버전 #을 설정해야 합니다.이상적이지는 않지만 기능적입니다.
