首先通过`adb`命令获取系统广播记录

```sh
adb shell dumpsys |grep BroadcastRecord
```



通过分析自己所需要的广播`action`，注册在自己的广播接收者，获取`extras`

```java
BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            Bundle bundle = intent.getExtras();
            StringBuilder info = new StringBuilder();
            if (bundle != null) {
                Set<String> getKey = bundle.keySet();
                for (String key : getKey) {
                    Object object = bundle.get(key);
                    if (object instanceof Integer) {
                        info.append("\n").append(key).append("==int==").append(object);
                    } else if (object instanceof String) {
                        info.append("\n").append(key).append("==String==").append(object);
                    } else if (object instanceof Boolean) {
                        info.append("\n").append(key).append("==boolean==").append(object);
                    } else {
                        if (object != null) {
                            info.append("\n").append(key).append("==").append(object.getClass()).append("==").append(object);
                        } else {
                            info.append("\n").append(key).append("==").append("null").append("==").append("null");
                        }
                    }
                }
                if (isOrderedBroadcast()) {
                    abortBroadcast();
                }
            } else {
                info = new StringBuilder("no extras");
            }
        }
    };
```
