以编程方式将APK推送到系统/应用程序

Question

我想以编程方式将APK推送到根设备上的system/app。我试过以下代码，但push似乎不是安卓上的命令。我如何修改它才能正常工作？

  public static void copyApkToSys(){
    Process process;
    try {
        process = Runtime.getRuntime().exec("su");
        DataOutputStream out = new DataOutputStream(process.getOutputStream());
        out.writeBytes("mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system\n");
        out.writeBytes("push /data/shareData/a1.apk /system/app\n");
        out.writeBytes("mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system\n");
        out.writeBytes("exit\n");  
        out.flush();
        process.waitFor();

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

如果我使用以下代码，应用程序只有在重启设备后才会出现：

public static void copyApkToSys(){
    Process process;
    try {
        process = Runtime.getRuntime().exec("su");
        DataOutputStream out = new DataOutputStream(process.getOutputStream());
        out.writeBytes("mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system\n");
        out.writeBytes("cat /data/shareData/a1.apk > /system/app/a1.apk\n");
        out.writeBytes("mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system\n");
        out.writeBytes("exit\n");  
        out.flush();
        process.waitFor();

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

}

编辑:如果我使用cat，那么使用下面的代码，但是我不能启动我的活动

public static boolean startApk(String packageName, String activityName) {
    boolean isSuccess = false;

    String cmd = "am start -n " + packageName + "/" + activityName + " \n";
    try {
        Process process = Runtime.getRuntime().exec(cmd);

        isSuccess = waitForProcess(process);
    } catch (IOException e) {

        e.printStackTrace();
    } 
    return isSuccess;
}

似乎在push和cat之间有区别，因为通过亚行推送应用程序会得到我想要的结果。我怎样才能以编程的方式做到这一点？

尝试使用命令"mv -R"，就像Linux命令一样
