Android app in Eclipse: Edit text not showing on Graphical layout

I am trying to add a text field onto my Android app in Eclipse, but then I drag the Plain text option on to the graphical layout, a message at the bottom comes up. It reads Exception raised during rendering: java.lang.System.arraycopy([CI[CII)V Exception details are logged in Window > Show View > Error Log Even when I go to Window > Show View there is no error log option. The whole designer is useless now, because I can not use it anymore until I delete the EditText directly from the xml. What is causing this error, and how do I fix it? I am running the latest version (as of today, 6-30-14), and Windows 8 Pro x64.

Here is my full layout code:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="${relativePackage}.${activityClass}" >

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="18dp"
    android:text="@string/welcome_text" />

<EditText
    android:id="@+id/editText1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:ems="10"
    android:inputType="text">

    <requestFocus />
</EditText>

</RelativeLayout>

Solution 1:

Check the "Android version to use when rendering layouts" and make sure you're not using a version that ends in "W" for Android Wear (e.g. API 20: Android 4.4W). I don't believe Wear supports EditText.

In both Android Studio and Eclipse, it's the dropdown with the green android in the layout preview's toolbar. You may want to set it explicitly and not allow the IDE to choose the Android version automatically.

Solution 2:

From the Eclipse IDE, just change the API version to use for previewing, as shown in below screenshot. Instead of "Automatically Pick Best", manually select the one which works for you (API 17 worked for me).

Solution 3:

I changed my Android version for Android 4.2, but it still not work for me. I tried different solutions found that it only work by deleting Android 4.4W package.

Window > Android SDK Manager > check Android 4.4W(API 20) if it was installed > Delete package

Solution 4:

If you are facing this on Android Studio, follow along

1) Uninstall Android 4.4W(API 20) from the SDK Manager

2) Make sure you have Android SDK Build Tools 19.1 installed from the SDK Manager.

3) Edit build.gradle within your app folder. Set the following two values as below

compileSdkVersion 19
buildToolsVersion "19.1"

4) The IDE will prompt you to sync the Gradle file with your project, click Yes.

5) Open your activity file and then change the 'Android version to use when rendering layouts in IDE' to 'API 19'. This is the green colored Android Bot towards the right on the preview window
