没有找到处理意图的活动 (act=android.intent.action.VIEW) 尝试安装 APK [英] No Activity Found to handle Intent (act=android.intent.action.VIEW) Trying to Install APK

问题描述

我正在尝试安装我刚刚下载的 APK.但是，当我利用 Intent 安装 APK 时，我收到错误 android.content.ActivityNotFoundException: No Activity found to handle Intent...这是我的来源:

I'm trying to install an APK that I just downloaded. However, when I utilize the intent to install the APK I get error android.content.ActivityNotFoundException: No Activity found to handle Intent... Here's my source:

class DownloadTask extends AsyncTask<String, Integer, String> {
    private Context context;
    private String output;
    private Boolean install;
    private String file;
    private PowerManager.WakeLock wakeLock;

    public DownloadTask(Context context, String output, String file, Boolean install) {
        this.context = context;
        this.output = output;
        this.install = install;
        this.file = file;
    }

    @Override
    protected String doInBackground(String... surl) {
        InputStream input = null;
        OutputStream output = null;
        HttpURLConnection c = null;
        try {
            URL url = new URL(surl[0]);
            c = (HttpURLConnection) url.openConnection();
            c.connect();
            if (c.getResponseCode() != HttpURLConnection.HTTP_OK)
                return "Server returned HTTP " + c.getResponseCode() + " " + c.getResponseMessage();
            int filelength = c.getContentLength();
            input = c.getInputStream();
            output = new FileOutputStream(this.output + this.file);
            byte data[] = new byte[4096];
            long total = 0;
            int count;
            while ((count = input.read(data)) != -1) {
                total += count;
                if (filelength > 0)
                    publishProgress((int) (total * 100 / filelength));
                output.write(data, 0, count);
            }
        } catch (Exception e) {
            return e.toString();
        } finally {
            try {
                if (output != null) output.close();
                if (input != null) input.close();
            } catch (IOException e) {
            }
            if (c != null) c.disconnect();
        }

        return null;
    }

    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
        wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, getClass().getName());
        wakeLock.acquire();
        pDialog.show();
    }

    @Override
    protected void onProgressUpdate(Integer... progress) {
        super.onProgressUpdate(progress);
        pDialog.setIndeterminate(false);
        pDialog.setMax(100);
        pDialog.setProgress(progress[0]);
    }

    @Override
    protected void onPostExecute(String result) {
        wakeLock.release();
        pDialog.dismiss();
        if (result != null)
            Toast.makeText(context, "Download error: " + result, Toast.LENGTH_LONG).show();
        else if (this.install) {
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setDataAndType(Uri.parse("file://" + this.output + this.file), "application/vnd.android.package-archive");
            this.context.startActivity(intent);
        }
    }

}

这是错误的堆栈跟踪:

推荐答案

问题与 apk 的名称不是原始名称有关.将其重命名为原来的名称有效.

The problem had to do with the fact that the name of the apk was not the original. Renaming it to its original name worked.
