Question

I’m building an application targeting all the devices for Android. But I’m not able to run the application specifically on Nexus 7. I have checked through all the possibilities present on the stackoverflow, but I’m not able to recover from this problem. I’m pasting my AndroidManifest file here. Please see and correct me where I’m doing wrong.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

        <meta-data

            android:resource="@xml/my_appwidget_info" />
    </receiver>

    <!-- Mobclix Required Parameter -->
    <meta-data
        android:name="com.mobclix.APPLICATION_ID"
        android:value="6D72xxxxx-xxxxxxxxxxxx-xxxxxxx" />

    <activity
        android:name="com.mobclix.android.sdk.MobclixBrowserActivity"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.Translucent.NoTitleBar" />
    <activity
        android:name="UserPreference"
        android:screenOrientation="portrait"
        android:theme="@android:style/Theme.NoTitleBar" >
    </activity>
</application>

Please give me some suggestion for that.

Answer 1

Worked for me! There was some problem with how I check my internet connection. Here is my solved code:

/**
 * Checking network state
 * */
public boolean connectionAvailable() {
    ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connectivityManager
            .getActiveNetworkInfo();
    return activeNetworkInfo != null;
}
