Android App Crashes on HTC and Sony Ericsson Phone

问题

We launched the app on the Market today - Nomad. I am getting reports that the app crashes on HTC and Sony Ericsson Phones. I got the following Log report from one of the USER.

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.m7.nomad/com.m7.nomad.SplashActivity}: java.lang.UnsupportedOperationException: Can't convert to dimension: type=0x3

Not able to understand why it happens.

SplashActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    context = this;

    // Remove title bar
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.activity_splash);

    // Shared Preferences
    settings = getSharedPreferences(SETTINGS_PREFS, 0);

    configRun = settings.getInt("database_version", 0);

    this.assetManager = this.getAssets();


}

Line 46 points to setContentView(R.layout.activity_splash);

activity_splash.java

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/primary_color" >

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:contentDescription="Splash Screen"
        android:gravity="center"
        android:src="@drawable/splash_logo" />

</RelativeLayout>

回答1:

Use this in your splash layout

<?xml version="1.0" encoding="utf-8"?>
 <ImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffe5492a"
android:contentDescription="Splash Screen"
android:scaleType="fitCenter"
android:src="@drawable/splash_logo" >

回答2:

The cause of your crash is likely tucked away in your styles. It likely contains an attribute referencing a dimension contained within the Android SDK, whereas you are running your application on an older version of the SDK that does not contain that dimension.

In this example, the author used the following attribute:

android:paddingLeft="?android:attr/listPreferredItemPaddingLeft"

However, as the accepted answer points out, the listPreferredItemPaddingLeft entry in android.R.attr is only available from SDK level 14 onwards.

Either remove the offending entries, replace them, or separate the resource files such that they respect the SDK level. For instance, you could provide one style in res/values-14, and another omitting those entries from the version in res/values.

Apply this xml in your project and see what happens :)

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@color/primary_color"
    android:textAlignment="center" >

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:contentDescription="Splash Screen"
        android:gravity="center"
        android:src="@drawable/splash_logo" />

</RelativeLayout>

Comment this line ::

context = this;
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
