Android 应用程序在 HTC 和索尼爱立信手机上崩溃

Question

我们今天在市场上发布了该应用程序 - Nomad .我收到有关该应用程序在 HTC 和索尼爱立信手机上崩溃的报告。我从一位用户那里得到了以下日志报告。

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

无法理解为什么会这样。

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();


}

第46行指向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>

崩溃的原因可能隐藏在您的样式中。它可能包含引用 Android SDK 中包含的维度的属性，而您在不包含该维度的旧版 SDK 上运行您的应用程序。

In this example ，作者使用了以下属性:

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

但是，正如已接受的答案所指出的那样，listPreferredItemPaddingLeft entry android.R.attr 仅适用于 SDK 级别 14 及更高版本。

要么删除有问题的条目，替换它们，要么分离资源文件，使其符合 SDK 级别。例如，您可以在 res/values-14 中提供一种样式，而在 res/values 中省略版本中的那些条目。
