Android PackageInstaller安装失败\u内部错误：会话已放弃

我在尝试使用软件包安装程序安装apk时遇到问题。安装失败，状态消息非常模糊：“安装失败\u内部错误：会话放弃”

以下是安装软件包的代码：

public static void installPackage(Context context, String packageName, String apkPath)
{
    Logger.debug("Installing package " + apkPath);
    PackageInstaller packageInstaller = context.getPackageManager().getPackageInstaller();

    PackageInstaller.SessionParams params = new PackageInstaller.SessionParams(PackageInstaller.SessionParams.MODE_FULL_INSTALL);
    params.setAppPackageName(packageName);

    try {
        Logger.debug("Creating session");
        int sessionId = packageInstaller.createSession(params);
        PackageInstaller.Session session = packageInstaller.openSession(sessionId);

        Logger.debug("Copying buffer");
        OutputStream out = session.openWrite(packageName, 0, -1);
        FileInputStream fileInputStream = new FileInputStream(new File(apkPath));

        byte[] buffer = new byte[1024];
        int len = fileInputStream.read(buffer);
        while(len != -1)
        {
            out.write(buffer,0, len);
            len = fileInputStream.read(buffer);
        }

        session.fsync(out);
        fileInputStream.close();
        out.close();

        Logger.debug("Buffer copied, sending intent");

        Intent intent = new Intent(INSTALL_COMPLETE_ACTION);
        IntentSender intentSender = PendingIntent.getBroadcast(context, sessionId,
                intent, 0) .getIntentSender();
        session.commit(intentSender);
        session.close();
    }
    catch(IOException e)
    {
        Logger.error("IOException while installing package");
        Logger.error(e);
    }
    catch(Exception e)
    {
        Logger.error("Unknown exception while installing package");
        Logger.error(e);
    }
}

以下是处理意图的广播接收器：

private BroadcastReceiver mInstallReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {

        Logger.debug("Received intent");
        Logger.debug("Intent action: " + intent.getAction());
        int status = intent.getIntExtra(PackageInstaller.EXTRA_STATUS, PackageInstaller.STATUS_FAILURE);
        Logger.debug("Intent status: " + status);
        String message = intent.getStringExtra(PackageInstaller.EXTRA_STATUS_MESSAGE);
        Logger.debug("Status message: " + message);

        if(status == PackageInstaller.STATUS_PENDING_USER_ACTION)
        {
            Intent innerIntent = (Intent) intent.getParcelableExtra(Intent.EXTRA_INTENT);
            startActivity(innerIntent);
        }
    }
};

下面是broadcastreceiver生成的日志：
