dfu升级适用于nordic nRF51 nRF52 的系统，github上提供了相关升级的库https://github.com/NordicSemiconductor/Android-DFU-Library 支持 Android 4.3+
gradle配置如下：
implementation 'no.nordicsemi.android:dfu:1.8.1'
在使用前请先配置好BLE的相关权限以及动态权限 读写权限 定位等可以使用EasyPermission配置
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_PRIVILEGED" />
第一步 我们创建一个service集成DfuBaseService
public class DfuService extends DfuBaseService {
public DfuService() {
}
@Override
protected Class<? extends Activity> getNotificationTarget() {
return NotificationActivity.class;
}
@Override
public IBinder onBind(Intent intent) {
// TODO: Return the communication channel to the service.
throw new UnsupportedOperationException("Not yet implemented");
}
}
第二步 创建一个NotificationActivity
public class NotificationActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// If this activity is the root activity of the task, the app is not running
if (isTaskRoot()) {
// Start the app before finishing
final Intent intent = new Intent(this, UpdateZipActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtras(getIntent().getExtras()); // copy all extras
startActivity(intent);
}
// Now finish, which will drop you to the activity at which you were at the top of the task stack
finish();
}
}
其中UpdateZipActivity即为处理升级业务的界面
在这里要根据你的业务需求来，可以把升级包打包在apk里，也可以做成下载后升级的情况
如果是打包在apk里可以按下面做，如果你是下载的情况只需要改starter.setZip(uri, path); 传入文件uri和路径即可
private DfuServiceInitiator starter;
starter = new DfuServiceInitiator(mac).setDeviceName("Smart Lock").setKeepBond(false).setPacketsReceiptNotificationsEnabled(true).setPacketsReceiptNotificationsValue(10);
// If you want to have experimental buttonless DFU feature supported call additionally:
starter.setUnsafeExperimentalButtonlessServiceInSecureDfuEnabled(true);
starter.setZip(R.raw.update24); //setDeviceName为设备过滤条件 setzip传入raw文件的路径即可
@Override
protected void onResume() {
DfuServiceListenerHelper.registerProgressListener(this, mDfuProgressListener); //监听升级进度
starter.start(this, DfuService.class); //启动升级服务
}
/**
* dfu升级监听
*/
private final DfuProgressListener mDfuProgressListener = new DfuProgressListener() {
@Override
public void onDeviceConnecting(String deviceAddress) {
Log.i("dfu", "onDeviceConnecting");
proBar.setIndeterminate(true);
airUpgradeTv.setText(R.string.dfu_status_connecting);
} @Override
public void onDeviceConnected(String deviceAddress) { } @Override
public void onDfuProcessStarting(String deviceAddress) {
proBar.setIndeterminate(true);
airUpgradeTv.setText(R.string.dfu_status_starting);
} @Override
public void onDfuProcessStarted(String deviceAddress) {
Log.i("dfu", "onDfuProcessStarted");
} @Override
public void onEnablingDfuMode(String deviceAddress) {
Log.i("dfu", "onEnablingDfuMode");
proBar.setIndeterminate(true);
airUpgradeTv.setText(R.string.dfu_status_switching_to_dfu);
} @Override
public void onProgressChanged(String deviceAddress, int percent, float speed, float avgSpeed, int currentPart, int partsTotal) {
Log.i("dfu", "onProgressChanged");
Log.i("dfu", "onProgressChanged" + percent);
proBar.setProgress(percent);
proBar.setIndeterminate(false);
airUpgradeTv.setText(percent + "%");
} @Override
public void onFirmwareValidating(String deviceAddress) {
Log.i("dfu", "onFirmwareValidating");
proBar.setIndeterminate(true);
airUpgradeTv.setText(R.string.dfu_status_validating);
} @Override
public void onDeviceDisconnecting(String deviceAddress) {
Log.i("dfu", "onDeviceDisconnecting");
} @Override
public void onDeviceDisconnected(String deviceAddress) {
Log.i("dfu", "onDeviceDisconnected");
proBar.setIndeterminate(true);
airUpgradeTv.setText(R.string.dfu_status_disconnecting); } @Override
public void onDfuCompleted(String deviceAddress) { airUpgradeTv.setText(R.string.dfu_status_completed);
proBar.setProgress(100);
proBar.setIndeterminate(false);
//升级成功
new Handler().postDelayed(new Runnable() {
@Override
public void run() { // if this activity is still open and upload process was completed, cancel the notification
final NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.cancel(DfuService.NOTIFICATION_ID); }
},200); } @Override
public void onDfuAborted(String deviceAddress) {
Log.i("dfu", "onDfuAborted");
//升级流产，失败
airUpgradeTv.setText(R.string.dfu_status_aborted);
// let's wait a bit until we cancel the notification. When canceled immediately it will be recreated by service again.
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Toast.makeText(UpdateZipActivity.this, "升级出错", Toast.LENGTH_SHORT).show();
// if this activity is still open and upload process was completed, cancel the notification
final NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.cancel(DfuService.NOTIFICATION_ID);
}
}, 200); } @Override
public void onError(String deviceAddress, int error, int errorType, String message) {
Log.i("dfu", "onError"); airUpgradeTv.setText(getString(R.string.dfu_status_aborted));
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
// if this activity is still open and upload process was completed, cancel the notification
final NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
manager.cancel(DfuService.NOTIFICATION_ID); }
}, 200); }
@Override
protected void onPause() {
//取消监听
DfuServiceListenerHelper.unregisterProgressListener(this, mDfuProgressListener);
super.onPause();
}
