手机要ROOT，然后用下面的代码试试

package com.sfer.install;
  
import android.app.Activity;
import android.os.Bundle;
import android.widget.Toast;
  
public class InstallActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        String paramString= "$ adb push MySMS.apk /sdcard/" +"\n"+
                "$ adb shell" +"\n"+
                "$ su" +"\n"+
                "# mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system" +"\n"+
                "# cat /sdcard/MySMS.apk > /system/app/MySMS.apk" +"\n"+
                "# mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 /system" +"\n"+
                "# exit" +"\n"+
                "$ exit";        
        if(RootCmd.haveRoot()){
            if(RootCmd.execRootCmdSilent(paramString)==-1){
                Toast.makeText(this, "安装不成功", Toast.LENGTH_LONG).show();
            }else{
                Toast.makeText(this, "安装成功", Toast.LENGTH_LONG).show();
            }
