Android : 프로그래밍 방식으로 .apk 설치


이 질문에는 이미 답변이 있습니다.

나는 안드로이드 다운로드 바이너리 파일 문제안드로이드에 프로그래밍 방식으로 응용 프로그램 설치의 도움으로 이것을 만들었습니다 .

자동 업데이트 및 자동 설치를 한 번에 만들고 싶습니다. 로컬이므로 시장이 아닌 응용 프로그램입니다.

여기 내 코드가 있습니다 :

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 INTERNET, WRITE_EXTERNAL_STORAGE, INSTALL_PACKAGES,와 DELETE_PACKAGES.

인 텐트 promptInstall가로드되면 앱이 충돌합니다 = /

따라서 권한이 없거나 코드가 잘못 되었습니까? 아니면 더 좋은 방법이 있습니까?


나는 문제를 해결했다. setData(Uri)에서 실수했습니다 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 작동하고 있습니다. 도와 줘서 고마워. =)

20.7.2016 편집 :

오랜 시간이 지난 후에 다른 프로젝트에서이 업데이트 방식을 다시 사용해야했습니다. 오래된 솔루션에 많은 문제가 발생했습니다. 그 당시 많은 것들이 바뀌 었으므로 다른 접근 방식 으로이 작업을 수행해야했습니다. 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));

ICS의 경우 코드를 구현하고 확장하는 클래스를 만들었습니다 AsyncTask. 감사합니다. 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;
    }
}   

이것을 사용하려면 주요 활동에서 다음과 같이 호출하십시오.

atualizaApp = new UpdateApp();
atualizaApp.setContext(getApplicationContext());
atualizaApp.execute("http://serverurl/appfile.apk");

이 질문은 매우 유용하지만 SD 카드를 에뮬레이터에 마운트하는 것을 잊지 마십시오.

나는 이것을 발견하기 전에 시간을 잃는다.

이것을 공유해 주셔서 감사합니다. 구현하고 작동했습니다. 하나:

1) 앱의 ver 1을 설치합니다 (문제 없음) 2) ver 2를 서버에 배치합니다. 응용 프로그램은 ver2를 검색하고 SD 카드에 저장하고 사용자에게 새 패키지 ver2를 설치하라는 메시지를 표시합니다. 3) ver2 설치 및 예상대로 작동합니다. 4) 문제는 응용 프로그램을 시작할 때마다 사용자가 버전 2를 다시 설치하기를 원한다는 것입니다.

그래서 해결책은 단순히 SD 카드에서 APK를 삭제하는 것이라고 생각했지만 비동기 작업은 단순히 서버에 대해 ver2를 다시 검색해야합니다.

따라서 v2 apk를 다시 설치하지 않으려는 유일한 방법은 sdcard 및 원격 서버에서 제거하는 것입니다.

알다시피, 모든 사용자가 최신 버전을 언제 받았는지 알 수 없으므로 실제로 작동하지 않을 것입니다.

이 문제를 해결하는 데 도움을 주시면 감사하겠습니다.

위에 나열된 "ldmuniz"방법을 구현했습니다.

새로운 편집 : APK의 이름이 모두 동일하다고 생각했습니다. myapk_v1.0xx.apk의 이름을 지정하고 해당 버전에서 v.2.0이 릴리스 될 때마다 원격 경로를 사전에 설정해야합니까?

나는 이론을 테스트했고 문제를 해결했다. 현재 출시 된 앱에서 항상 NEXT 릴리스 버전 #을 설정해야한다는 것을 기억하여 APK 파일 파일의 이름을 일종의 버전 관리로 지정해야합니다. 이상적이지 않고 기능적입니다.
