public boolean checkNetwork() {
boolean result = false;
try {
Context context = this.getApplicationContext();
ConnectivityManager connectivityMgr = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connectivityMgr.getActiveNetworkInfo();
if (networkInfo != null) {
result = networkInfo.isAvailable();
}
}
catch (Exception e) {
Log.e("test", "get active network info leave: " + e.getMessage());
}
return result;
}
简单的网络检查，却在connectivityMgr.getActiveNetworkInfo();时抛出如下异常：
java.lang.SecurityException: ConnectivityService: Neither user 10037 nor current process has android.permission.ACCESS_NETWORK_STATE.
原因：SecurityException，显然是权限不够。
解决方案：在AndroidManifest.xml中，加入如下权限：
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
