android更新apk方式

禁默安装

App 内升级调用 PackageInstaller

public static void installApk1(
          final @NonNull File apkFile, final @NonNull PermissionsActivity permissionsActivity) {
    String apkName = "appInstall.apk";
    long apkFileLength = apkFile.length();

    PackageInstaller packageInstaller = pm.getPackageInstaller();

        Log.e(TAG, "Install Start sessionId-> " + sessionId);
      }

      @Override
      public void onBadgingChanged(int sessionId) {}

      @Override
      public void onActiveChanged(int sessionId, boolean active) {}

      public void onProgressChanged(int sessionId, float progress) {}

        } else {
          Log.e(TAG, "Silent Install Fail");
        }
      }
    });

    int count;
    int sessionId;
    byte[] buffer = new byte[65536];

    InputStream inputStream;
    OutputStream outputStream;
    PackageInstaller.Session session = null;
    PackageInstaller.SessionParams sessionParams;

    try {
      sessionParams = new PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL);
      sessionId =  packageInstaller.createSession(sessionParams);
      session = packageInstaller.openSession(sessionId);

      inputStream = new FileInputStream(apkFile);
      outputStream = session.openWrite(apkName, 0, apkFileLength);

      while((count = inputStream.read(buffer)) != -1) {
        outputStream.write(buffer, 0, count);
        float progress = ((float)count / (float)apkFileLength);
        session.setStagingProgress(progress);
      }
      session.fsync(outputStream);

      inputStream.close();
      outputStream.flush();
      outputStream.close();

      Intent intent = new Intent();
      intent.setAction("xinan.intent.action.APP_INSTALL");
      PendingIntent pendingIntent = PendingIntent.getBroadcast(permissionsActivity.getBaseContext(), 0, intent, 0);
      session.commit(pendingIntent.getIntentSender());
    } catch (Exception e) {
      e.printStackTrace();
      if (session != null) {
        session.abandon();
      }
    } finally {
    }
  }
