是否有可能因 lint 检查错误而导致 Android Studio 构建失败?当我将图标从 .png 转换为矢量可绘制 .xml 时,我遇到了 ImageViews 问题。有时我忘记更改为,
android:src="@drawable/ic_minus"
并且
app:srcCompat="@drawable/ic_minus"
应用程序在较旧的操作系统设备上崩溃。

当尝试使用 Firebase Cloud Function 内的库发送邮件时nodemailer。我收到错误:
Billing account not configured. External network is not accessible and quotas are severely limited. Configure billing account to remove these restrictions

我刚刚开始使用Android Concurrency / Loopers / Handers玩游戏,而且刚遇到奇怪的异常情况。下面的代码不会阻止我从其他线程在TextView上设置文本。
TextView tv;
Handler backgroundHandler;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv = (TextView) findViewById(R.id.sample_text);
Runnable run = new Runnable() {
@Override
public void run() {
Looper.prepare();
backgroundHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
String text = (String) msg.obj;
tv.setText(Thread.currentThread().getName() + " " + text);
}
};
Looper.loop();
}
};
Thread thread = new Thread(run);
thread.setName("Background thread");
thread.start();
try {
Thread.sleep(100);
} catch (InterruptedException e) {
e.printStackTrace();
}
