极光推送使用心得（简单使用）

1.使用android studio 自动集成包

  defaultConfig {
        ......
        ndk {
            //选择要添加的对应cpu类型的.so库。
            abiFilters 'armeabi'
            // 还可以添加 'x86', 'x86_64', 'mips', 'mips64'
        }
        manifestPlaceholders = [
                JPUSH_PKGNAME: applicationId,
                JPUSH_APPKEY : "你申请的appkey", //JPush上注册的包名对应的appkey.
                JPUSH_CHANNEL: "developer-default", //暂时填写默认值即可.
        ]
    }

2.AndroidManifest.xml里面静态注册BroadcastReceiver

3.写一个自定义接收器

/**
 * 自定义接收器
 * 

 * 如果不定义这个 Receiver，则：
 * 1) 默认用户会打开主界面
 * 2) 接收不到自定义消息
 */
public class MyReceiver extends BroadcastReceiver {
    private static final String TAG = "JPush";

    @Override
    public void onReceive(Context context, Intent intent) {
        Bundle bundle = intent.getExtras();
        Log.d(TAG, "[MyReceiver] onReceive - " + intent.getAction() + ", extras: " + printBundle(bundle));

        if (JPushInterface.ACTION_REGISTRATION_ID.equals(intent.getAction())) {

            String regId = bundle.getString(JPushInterface.EXTRA_REGISTRATION_ID);
            Log.d(TAG, "[MyReceiver] 接收Registration Id : " + regId);
            //send the Registration Id to your server...

        } else if (JPushInterface.ACTION_MESSAGE_RECEIVED.equals(intent.getAction())) {
            Log.d(TAG, "[MyReceiver] 接收到推送下来的自定义消息: " + bundle.getString(JPushInterface.EXTRA_MESSAGE));
            processCustomMessage(context, bundle);

        } else if (JPushInterface.ACTION_NOTIFICATION_RECEIVED.equals(intent.getAction())) {
            Log.d(TAG, "[MyReceiver] 接收到推送下来的通知");
            int notifactionId = bundle.getInt(JPushInterface.EXTRA_NOTIFICATION_ID);
            Log.d(TAG, "[MyReceiver] 接收到推送下来的通知的ID: " + notifactionId);

        } else if (JPushInterface.ACTION_NOTIFICATION_OPENED.equals(intent.getAction())) {
            Log.d(TAG, "[MyReceiver] 用户点击打开了通知");

            //打开自定义的Activity
            Intent i = new Intent(context, InformationActivity.class);
            //i.putExtras(bundle);
            i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            //i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP );
            context.startActivity(i);

        } else if (JPushInterface.ACTION_RICHPUSH_CALLBACK.equals(intent.getAction())) {
            Log.d(TAG, "[MyReceiver] 用户收到到RICH PUSH CALLBACK: " + bundle.getString(JPushInterface.EXTRA_EXTRA));
            //在这里根据 JPushInterface.EXTRA_EXTRA 的内容处理代码，比如打开新的Activity， 打开一个网页等..

        } else if (JPushInterface.ACTION_CONNECTION_CHANGE.equals(intent.getAction())) {
            boolean connected = intent.getBooleanExtra(JPushInterface.EXTRA_CONNECTION_CHANGE, false);
            Log.w(TAG, "[MyReceiver]" + intent.getAction() + " connected state change to " + connected);
        } else {
            Log.d(TAG, "[MyReceiver] Unhandled intent - " + intent.getAction());
        }
    }

    // 打印所有的 intent extra 数据
    private static String printBundle(Bundle bundle) {
        StringBuilder sb = new StringBuilder();
        for (String key : bundle.keySet()) {
            if (key.equals(JPushInterface.EXTRA_NOTIFICATION_ID)) {
                sb.append("\nkey:" + key + ", value:" + bundle.getInt(key));
            } else if (key.equals(JPushInterface.EXTRA_CONNECTION_CHANGE)) {
                sb.append("\nkey:" + key + ", value:" + bundle.getBoolean(key));
            } else if (key.equals(JPushInterface.EXTRA_EXTRA)) {
                if (TextUtils.isEmpty(bundle.getString(JPushInterface.EXTRA_EXTRA))) {
                    Log.i(TAG, "This message has no Extra data");
                    continue;
                }

                try {
                    JSONObject json = new JSONObject(bundle.getString(JPushInterface.EXTRA_EXTRA));
                    Iterator it = json.keys();

                    while (it.hasNext()) {
                        String myKey = it.next().toString();
                        sb.append("\nkey:" + key + ", value: [" +
                                myKey + " - " + json.optString(myKey) + "]");
                    }
                } catch (JSONException e) {
                    Log.e(TAG, "Get message extra JSON error!");
                }

            } else {
                sb.append("\nkey:" + key + ", value:" + bundle.getString(key));
            }
        }
        return sb.toString();
    }

    //send msg to MainActivity
    private void processCustomMessage(Context context, Bundle bundle) {
        if (MainActivity.isForeground) {
            String message = bundle.getString(JPushInterface.EXTRA_MESSAGE);
            String extras = bundle.getString(JPushInterface.EXTRA_EXTRA);
            Intent msgIntent = new Intent(MainActivity.MESSAGE_RECEIVED_ACTION);
            msgIntent.putExtra(MainActivity.KEY_MESSAGE, message);
            if (!ExampleUtil.isEmpty(extras)) {//复制极光demo里的ExampleUtil就好
                try {
                    JSONObject extraJson = new JSONObject(extras);
                    if (extraJson.length() > 0) {
                        msgIntent.putExtra(MainActivity.KEY_EXTRAS, extras);
                    }
                } catch (JSONException e) {

                }

            }
            context.sendBroadcast(msgIntent);
        }
    }
}

4.MainActivity中写接受广播

   public static boolean isForeground = false;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        JPushInterface.setDebugMode(true);
        JPushInterface.init(this);
        String regist = JPushInterface.getRegistrationID(this);
        Log.e("regist_person", regist);
        registerMessageReceiver();
  }

    @Override
    protected void onResume() {
        isForeground = true;
        super.onResume();
  }
   @Override
    protected void onPause() {
        isForeground = false;
        super.onPause();
  }
  @Override
    protected void onDestroy() {
        unregisterReceiver(mMessageReceiver);
        super.onDestroy();
  }
  private MessageReceiver mMessageReceiver;
    public static final String MESSAGE_RECEIVED_ACTION = "com.example.jpushdemo.MESSAGE_RECEIVED_ACTION";
    public static final String KEY_TITLE = "title";
    public static final String KEY_MESSAGE = "message";
    public static final String KEY_EXTRAS = "extras";

    public void registerMessageReceiver() {
        mMessageReceiver = new MessageReceiver();
        IntentFilter filter = new IntentFilter();
        filter.setPriority(IntentFilter.SYSTEM_HIGH_PRIORITY);
        filter.addAction(MESSAGE_RECEIVED_ACTION);
        registerReceiver(mMessageReceiver, filter);
    }

    public class MessageReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {
            if (MESSAGE_RECEIVED_ACTION.equals(intent.getAction())) {
                String messge = intent.getStringExtra(KEY_MESSAGE);
                String extras = intent.getStringExtra(KEY_EXTRAS);
                StringBuilder showMsg = new StringBuilder();
                showMsg.append(KEY_MESSAGE + " : " + messge + "\n");
                if (!ExampleUtil.isEmpty(extras)) {
                    showMsg.append(KEY_EXTRAS + " : " + extras + "\n");
                }
                Constant.showToast(MainActivity.this, showMsg.toString());
            }
        }
    }
