开机广播的接收

  1. 在Mainifest文件里静态注册
        <receiver android:name=".BootCompleteReceiver">            <intent-filter>                <action android:name="android.intent.action.BOOT_COMPLETED"></action>            </intent-filter>        </receiver>
  1. 在广播接收类中重写onReceive方法,启动检测的后台服务
public class BootCompleteReceiver extends BroadcastReceiver{    String TAG="BoostCompleteReceiver";    @Override    public void onReceive(Context context, Intent intent) {        Log.d(TAG,"boost receive ...");        Intent service = new Intent(context,DetectService.class);        context.startService(service);    }}
  1. 工具类FileProcessBinder的实现,结合之前

防丢App记录(2)–将序列号通过文件存储
只是假如文件名封装起来,这里因为存文件要用到Context,所以就将Context当做参数传进去了,,,这样不好,,心怀咯噔往前走,,,

/** FileProcessBinder* 文件保存工具类*/public class FileProcessBinder {    private Context context;    private String fileName;    String TAG = "FileProcessBinder";    public FileProcessBinder(Context context) {        this.context = context;    }    public FileProcessBinder(String fileName, Context context) {        this.fileName = fileName;        this.context = context;    }    public String load(String fileName) {        FileInputStream in = null;        BufferedReader reader = null;        StringBuilder content = new StringBuilder();        try {            in = context.openFileInput(fileName);            reader = new BufferedReader(new InputStreamReader(in));            String line = null;            while ((line = reader.readLine()) != null) {                content.append(line);                Log.d(TAG, "load:" + content.toString());            }        } catch (FileNotFoundException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        } finally {            if (reader != null) {                try {                    reader.close();                } catch (IOException e) {                    e.printStackTrace();                }            }        }        return content.toString();    }    public void save(String te1,String fileName) {        BufferedWriter writer = null;        try {            FileOutputStream mFileOutputStream = null;            mFileOutputStream = context.openFileOutput(fileName, Context.MODE_PRIVATE);            writer = new BufferedWriter(new OutputStreamWriter(mFileOutputStream));            writer.write(te1);            Log.d(TAG, "save:" + te1);        } catch (FileNotFoundException e) {            e.printStackTrace();        } catch (IOException e) {            e.printStackTrace();        } finally {            if (writer != null) {                try {                    writer.close();                } catch (IOException e) {                    e.printStackTrace();                }            }        }    }}
