Java 是否从应用程序中安装.zip？

因此，在我的应用程序中，我试图使用此工具使其在时钟恢复中闪烁.zip

 Runtime run = Runtime.getRuntime();
                      Process p = null;
                      DataOutputStream out = null;
                      try{
                          p = run.exec("su");
                          out = new DataOutputStream(p.getOutputStream());
                          out.writeBytes("echo install_zip SDCARD:" +clickedFile.toString() +" > /cache/recovery/extendedcommand\n");
                          out.writeBytes("reboot recovery\n"); // testing
                          out.flush();

                      }catch(Exception e){
                          Log.e("FLASH", "Unable to reboot into recovery mode:", e);
                          e.printStackTrace();

                      }

它将启动恢复，但不会刷新.zip。。怎么了。。哦，如果您需要完整的.java文件，这里是：

adb

命令如下所示：

adb shell
echo 'install_zip("/sdcard/update.zip");' > /cache/recovery/extendedcommand

我也有同样的问题，但是我使用了一个ListView和一个ArrayAdapter来返回文件的完整路径。当我尝试以“SDCARD:”的形式传递路径，后跟文件的路径时，无法找到该文件，因为新版本的CWM Recovery似乎不再支持该方法。但我发现了一个简单的解决方法：

    public boolean installPackage(String pos) throws InterruptedException {
    final String location = "/emmc/" + pos.substring(11);
    Process process = null;
    try {
        process = Runtime.getRuntime().exec("su");
        DataOutputStream os = new DataOutputStream(process.getOutputStream());
        os = new DataOutputStream(process.getOutputStream());
        os.writeBytes("echo 'install_zip(\"" + location + "\");'" + " > /cache/recovery/extendedcommand\n");
        os.writeBytes("reboot recovery\n");
        os.writeBytes("exit\n");
        os.flush();
        return (process.waitFor() == 0);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        Log.e("FLASH:", "Unable to boot into recovery");
        e.printStackTrace();
    }
        return false;
}

我会尝试用分号将echo和重启写在一行上，比如：

echo；重新启动…

。这应该保证序列化。

    public boolean installPackage(String pos) throws InterruptedException {
    final String location = "/emmc/" + pos.substring(11);
    Process process = null;
    try {
        process = Runtime.getRuntime().exec("su");
        DataOutputStream os = new DataOutputStream(process.getOutputStream());
        os = new DataOutputStream(process.getOutputStream());
        os.writeBytes("echo 'install_zip(\"" + location + "\");'" + " > /cache/recovery/extendedcommand\n");
        os.writeBytes("reboot recovery\n");
        os.writeBytes("exit\n");
        os.flush();
        return (process.waitFor() == 0);
    } catch (IOException e) {
        // TODO Auto-generated catch block
        Log.e("FLASH:", "Unable to boot into recovery");
        e.printStackTrace();
    }
        return false;
}
