在 Activity 的 mainThread 中使用了我的图像处理程序和 Exo 播放器（用于播放音乐）。OS-9 (Nokia) 设备中的螺母无法正常工作 imageHandler -> 连接到 Workhandler。代码下方：WorkHandler
public class WorkHandler extends android.os.HandlerThread {
private Handler workHandler = null;
private volatile List<WorkMessageProxy> messageProxyList;
public WorkHandler() {
super("WorkHandler", Process.THREAD_PRIORITY_BACKGROUND);
start();
workHandler = new Handler(getLooper()) {
@Override
public void handleMessage(Message msg) {
if (messageProxyList != null) {
for (WorkMessageProxy workMessageProxy : messageProxyList) {
Log.i("workHandler", "handleMessage: Message: " + msg.toString());
workMessageProxy.handleMessage(msg);
}
}
}
};
}
public void post(Runnable run) {
workHandler.post(run);
}
public void postAtFrontOfQueue(Runnable runnable) …在将Android Studio 3.3更新到3.4之后，它会出现错误。出现了一个错误，即AAPT2，这为我提供了一个建议我喜欢这样的错误：
此构建中使用了不推荐使用的Gradle功能，使其与Gradle 6.0不兼容。使用“ --warning-mode all”来显示各个弃用警告。看到
gradle.properties
org.gradle.warning.mode=all
但仍然无法正常工作。
错误：
