Android客制化------开机拷贝文件到内置存储

此方法尽量不要拷贝大文件
在Service中进行拷贝动作

package com.xxx.filecopy;import android.app.Service;import android.content.Context;import android.content.Intent;import android.content.SharedPreferences;import android.os.AsyncTask;import android.os.IBinder;import java.io.File;public class CopyService extends Service {    private final Context mContext;    private String srcPath = "/system/extMedia/";    private String dstPath = "/mnt/sdcard/";    public CopyService() {        mContext = CopyService.this;    }    @Override    public void onCreate() {        super.onCreate();        new AsyncTask<Integer, Integer, Integer>() {            @Override            protected Integer doInBackground(Integer... params) {                // TODO Auto-generated method stub                Utils.log("onStart()");                SharedPreferences preference = (CopyService.this).getSharedPreferences("com.xxx.filecopy", MODE_PRIVATE);                boolean alreadyRun = preference.getBoolean("runed", false);                if(!alreadyRun){                    File sdcard = new File("/mnt/sdcard/");                    while(true){                        try{                            Thread.sleep(2000);                        }catch(Exception e){                            Utils.log("sd Can't write, wait 2 secounds");                        }                        // 判断sd卡是否为空且是否可写                        if(null != sdcard && sdcard.canWrite())                            break;                    }                    boolean b = Utils.copyDirectory(srcPath, dstPath);                    if(b){                        Utils.log("Copy successful !");                        Utils.scanFileAsync(mContext,dstPath);                        SharedPreferences.Editor editor = preference.edit();                        editor.putBoolean("runed", true);                        editor.commit();                        //播放视频                        Utils.playmp4(mContext);                    }                }                mContext.stopService(new Intent(mContext, CopyService.class));                return null;            }        }.execute(0);    }    @Override    public IBinder onBind(Intent intent) {        return null;    }}

第一次开机之后启动Service

package com.xxx.filecopy;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.SharedPreferences;import android.view.Gravity;import static android.content.Context.MODE_PRIVATE;public class Receiver extends BroadcastReceiver {    private static final String BOOT_COMPLETED = "android.intent.action.BOOT_COMPLETED";    private static final String DONT_TOUCH = "xxx.xxx.donttouch";    private Context mContext;    @Override    public void onReceive(Context context, Intent intent) {        // TODO: This method is called when the BroadcastReceiver is receiving        // an Intent broadcast.        String action = intent.getAction();        mContext = context;        Utils.log("action *****" + action);        SharedPreferences preference = context.getSharedPreferences("com.xxx.filecopy", MODE_PRIVATE);        boolean alreadyRun = preference.getBoolean("runed", false);        if (action.equals(BOOT_COMPLETED))        {            Intent i = new Intent();            i.setClass(context, CopyService.class);            i.setFlags(i.FLAG_ACTIVITY_NEW_TASK);            context.startService(i);            if (alreadyRun){                Utils.log("RE_BOOT_COMPLETED,SO NEED PLAY");                Utils.playmp4(mContext);            }        }else if (action.equals(DONT_TOUCH))        {            if (!Utils.isMusicActive(mContext))            {                Utils.log("Media will play");                Utils.playmp4(mContext);            }        }        String language = locale.getLanguage();        if (language.endsWith("ar"))        {            mNowContent.setGravity(Gravity.RIGHT| Gravity.TOP);        }    }}
