我正在关注如何制作自定义表盘的本教程。在复制代码并正确设置项目后（除了为每只手表制作动态坐标），我不知道如何实际运行该应用程序。我将在此处发布项目和代码：
和代码：

/* device features */
boolean mLowBitAmbient;
boolean mBurnInProtection;
float textY = 135;
float textSize = 20;
/* graphic objects */

Paint mTextPaint;
/* handler to update the time once a second in interactive mode */
final Handler mUpdateTimeHandler = new Handler() {
@Override
public void handleMessage(Message message) {
switch (message.what) {
case MSG_UPDATE_TIME:
invalidate();
if (shouldTimerBeRunning()) {
long timeMs = System.currentTimeMillis();
long delayMs = INTERACTIVE_UPDATE_RATE_MS
- (timeMs % INTERACTIVE_UPDATE_RATE_MS);
mUpdateTimeHandler
.sendEmptyMessageDelayed(MSG_UPDATE_TIME, delayMs);
}
break;
}
}
};
/* receiver to update the time zone */
final BroadcastReceiver mTimeZoneReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
mTime.clear(intent.getStringExtra("time-zone"));
mTime.setToNow();

大部分还没有做太多，我只是想测试一下我的绘图机制

我不知道如何测试运行这个东西。消息显示“未找到活动”，但我正确地遵循了教程。我已经制作了android应用程序，这让我很困惑。
（我不想要我的绘图代码的提示和东西，我只想知道我需要做什么才能运行它）
编辑：我不想从“开始...”开始应用程序
