Android 开发常见问题总结

问题：Android之NetworkOnMainThreadException异常

解决方式 ，使用多线程，异步加载的方式加载数据：

/**
* 异步的Post请求
* @param urlStr
* @param params
* @param callBack
* @throws Exception
*/
public static void doPostAsyn(final String urlStr, final String params
) throws Exception
{
new Thread()
{
public void run()
{
try
{
String result = doPost(urlStr, params);
// if (callBack != null)
// {
//      callBack.onRequestComplete(result);
// }
} catch (Exception e)
{
e.printStackTrace();
}

};
}.start();

}

问题：Android真机（手机）访问本机的tomcat导致，

java.net.ConnectException: failed to connect to localhost/127.0.0.1 (port 8080)

问题原因：Android真机（手机）和本机的tomcat不在同一个网段。

解决方式：在本机用（360免费wifi）分享一个无线网，Android真机（手机）连接分享的无线网。

To run dex in process, the Gradle daemon needs a larger heap.
It currently has approximately 910 MB.
For faster builds, increase the maximum heap size for the Gradle daemon to more than 2048 MB.
To do this set org.gradle.jvmargs=-Xmx2048M in the project gradle.properties.
