Android 蓝牙强度Rssi

FIWNKNS: 贴个我写的Kotlin的： when(deviceList[position].bluetoothClass.majorDeviceClass) { COMPUTER -> holder.deviceIcon.setImageResource(R.drawable.ic_baseline_computer_24) PHONE -> holder.deviceIcon.setImageResource(R.drawable.ic_baseline_smartphone_24) AUDIO_VIDEO -> holder.deviceIcon.setImageResource(R.drawable.ic_baseline_headphones_24) else -> holder.deviceIcon.setImageResource(R.drawable.ic_baseline_bluetooth_24) }

心有余悸525: 感谢分享，虽然还有点迷，但对内存的理解提高了一个档次

zhangbh2014: if(state == BluetoothAdapter.STATE_CONNECTED) 这个我觉得不用，不然老是进不去里面的代码。去掉后结果是正确的，对于经典蓝牙。我自己也封装了一个，包含BLE的

czl123czl123: case FAILED_TRANSACTION: { ALOGE("!!! FAILED BINDER TRANSACTION !!! (parcel size = %d)", parcelSize); const char* exceptionToThrow; char msg[128]; if (canThrowRemoteException && parcelSize > 200*1024) { // bona fide large payload exceptionToThrow = "android/os/TransactionTooLargeException"; snprintf(msg, sizeof(msg)-1, "data parcel size %d bytes", parcelSize); } else { exceptionToThrow = (canThrowRemoteException) ? "android/os/DeadObjectException" : "java/lang/RuntimeException"; snprintf(msg, sizeof(msg)-1, "Transaction failed on small parcel; remote process probably died"); } jniThrowException(env, exceptionToThrow, msg); } break;

czl123czl123: 我撸了一下源码，发现binder传递的数据大小超过限制并不是40KB，而是200KB，同时打印这个错误日志时并不仅仅只是超过限制会打印，当发生了服务端异常崩溃等情况也会导致这个错误。
