Please help me to find out where I\'m going wrong, I am currently on Android 4.3, API 18,

I\'ve tried Android 4.0.3 API 15, Android 4.4W API 20; I have also tried editing sdk as below, but no luck.

<uses-sdk
   android:minSdkVersion=\"15\"
   android:targetSdkVersion=\"19\" />

回答1:

4.4W is Android Wear SDK. (dont target to android wear device)

try changing target sdk version to 19

check here targetSdkVersion setting

Do not use API Level of 20 and Platform 4.4W (which is Android Wear SDK) as Android Virtual Device.

Use API level 19 and platform 4.4.2 everything works fine.

回答2:

I had the same issue. But sdk version was not the cause for this exception.

In the AndroidManifest.xml file you have the theme has ActionBar in it.

android:theme=\"@style/AppTheme\" >

Change the above line to

android:theme=\"@android:style/Theme.DeviceDefault\" >

That will fix the exception.

回答3:

4.4W is Android Wear SDK.

This error is because the device you are targeting is Android Wear which has a different design pattern.

If you are developing a mobile application, change your AVD and target any API below 20 or choose API 20 (L preview).

Or if you are really targeting for Android Wear, change your app design.

回答4:

Am using Android Studio beta 0.8.6 with java 7. I had the same issue. And fixed it this way.

In the AndroidManifest.xml file you have the theme has ActionBar in it.

android:theme=\"@style/AppTheme\" >

Change the above line to

android:theme=\"@android:style/Theme.DeviceDefault\" >

That will fix the exception. As mentioned by Gangadhar in prev answer ,sdk version was not the cause for this exception.

And tested it with helloWorld app.

回答5:

I got this error because I tried to run the mobile part of a wear project on the Samsung Gear device. After switching from \"mobile\" to \"wear\" in the run configurations, everything worked (API level 20 and platform 4.4W is indeed the right choice in this case).

回答6:

I got this problem when trying to create the project in Eclipse.
I had to add the following to the manifest file:

<uses-feature android:name=\"android.hardware.type.watch\" />

回答7:

go to values/styles.xml and set the styles as follow:

<resources>

    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
    -->
    <style name=\"AppBaseTheme\" parent=\"android:Theme.DeviceDefault\">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.
        -->
    </style>

    <!-- Application theme. -->
    <style name=\"AppTheme\" parent=\"AppBaseTheme\">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
    </style>

</resources>

Also, in folders res/values-v11 and res/values-v14, and all folders in values-vxx change the styles.xml file as follows:

<resources>

    <!--
        Base application theme for API 14+. This theme completely replaces
        AppBaseTheme from BOTH res/values/styles.xml and
        res/values-v11/styles.xml on API 14+ devices.
    -->
    <style name=\"AppBaseTheme\" parent=\"android:Theme.DeviceDefault\">
        <!-- API 14 theme customizations can go here. -->
    </style>

</resources>

You have not to add action bar themes as they are not compatible with wear devices.

回答8:

Change target sdk version to 19

Install API level 19 and platform 4.4.2

Use API level 19 & platform 4.4.2 while running application in AVD.

回答9:

I have struggle a lot to fix the issue. Nothing work for me except the changes I made in AndroidManifest.xml.

<uses-sdk
        android:minSdkVersion=\"7\"
        android:targetSdkVersion=\"21\" />

Remove android:targetSdkVersion, it worked for me, you can also try.
