我是Android开发的新手,现在已经停留了几天。虽然很多人都得到了相同的错误答案提交似乎并没有帮助我。我有一个启动画面5秒钟,然后启动我的第二个活动,这只是一个webview。 (旁注:如果我不使用互联网权限,第二个活动启动没有问题,但我确实得到一个网页不可用的屏幕,当我包含权限时,应用程序崩溃后闪屏)这是我的代码;
MainActivity:
public class MainActivity extends Activity {
Thread newTimer;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
newTimer = new Thread() {
public void run(){
try{
sleep(3000);
}
catch(InterruptedException e){
e.printStackTrace();
}
finally
{
Intent nw = new Intent(MainActivity.this, SecondActivity.class);
startActivity(nw);
}
}
};
newTimer.start();
}
}
SecondActivity:
public class SecondActivity extends Activity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.secondlayout);
String url = "http://ythaber.com/";
WebView myWebWiew = (WebView) this.findViewById(R.id.webView1);
myWebWiew.setWebViewClient(new WebViewClient());
myWebWiew.getSettings().setJavaScriptEnabled(true);
myWebWiew.loadUrl(url);
}
AndroidManifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.idpturkey.ythaber2"
android:versionCode="1"

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="SecondActivity" >
</activity>
</application>
</manifest>
logcat的:

提前致谢, Devrim
答案 0 :(得分:1)
从secondlayout.xml
<uses-permission
android:name="android.permission.INTERNET" >
</uses-permission>
将其放入项目中的ManifestFile.xml
。
您的所有权限应写在Manifest.xml
而不是your_layout.xml
希望它会对你有所帮助。
