Android 盒子静默安装apk方法之一

安装代码做个笔记
//静默安装

private static int cmdInstallApk(String apkPath) {
    String cmd = ("pm install -r " + apkPath);
    DataOutputStream dataOutputStream = null;
    try {
        //手机必须root
        Process process = Runtime.getRuntime().exec("su");// (这里执行是系统已经开放了root权限，而不是说通过执行这句来获得root权限)
        dataOutputStream = new DataOutputStream(
                (OutputStream) process.getOutputStream());
        // 部分手机Root之后Library path 丢失，导入path可解决该问题
        dataOutputStream.writeBytes((String) "export LD_LIBRARY_PATH=/vendor/lib:/system/lib\n");
        cmd = String.valueOf(cmd);
        dataOutputStream.writeBytes((String) (cmd + "\n"));
        dataOutputStream.flush();
        dataOutputStream.writeBytes("am start -n " + “包名” + "/" +“包名” + ".MainActivity" + " \n");
        dataOutputStream.flush();
        process.waitFor();
        return process.exitValue();
    } catch (Exception localException) {
        LogUtils.e(localException.getMessage());
        return -1;
    } finally {
        if (dataOutputStream != null) {
            try {
                dataOutputStream.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
