java - android 应用程序中的红外线实现导致它崩溃

Question

如果我取消注释我的方法 sendIrCode 中的任何代码，那么我的应用程序将在按下按钮时崩溃，该按钮运行方法 sendIrCode。虽然采用这种格式，但我可以获得 We have liftoff 和 Ultra liftoff 打印到屏幕上，但就像我之前说的那样，一旦我取消注释传输它就会崩溃。我已经尝试在两部不同的手机上运行这段代码，并且都可以使用 hasiremitter() 方法并像他们应该的那样返回 true，但这是我能够正常工作的 ConsumerIrManager 的唯一功能，任何帮助将不胜感激。

我还逐字使用了此链接中的代码位，没有任何变化。 https://android.googlesource.com/platform/development/+/master/samples/ApiDemos/src/com/example/android/apis/hardware/ConsumerIr.java

public class MainActivity extends ActionBarActivity {

ConsumerIrManager mCIR;

@Override

    super.onCreate(savedInstanceState);

    mCIR = (ConsumerIrManager)getSystemService("consumer_ir");

    setContentView(R.layout.activity_main);
}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

public void sendIrCode(View view) {

    int[] pattern = {338,169,21,63,21,63,21,63,21,63,21,63,21,63,21,63,21,63,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,21,63,21,21,21,63,21,63,21,63,21,63,21,63,21,63,21,21,21,63,21};

    //mCIR.transmit(37500, pattern);
    int button_id = Integer.parseInt(view.getTag().toString());

        //noinspection ResourceType
        mCIR = (ConsumerIrManager) getSystemService(Context.CONSUMER_IR_SERVICE);

            textView.setText("WE HAVE LIFTOFF!");

                    break;

                default:
                    break;

因此 API 文档甚至没有暗示您需要请求 Ifrared 许可这一事实，因此通过在我的 list 文件中看到它，我能够解决我的问题

http://developer.android.com/reference/android/Manifest.permission.html#TRANSMIT_IR

Answer 1

你的问题里面有答案:

 Caused by: java.lang.SecurityException: Requires TRANSMIT_IR permission
