怎么了:
是它没有显示哪个类导致了此崩溃。
用过
字体
代码:
private void setDefaultFont() {
try {
final Typeface bold = Typeface.createFromAsset(getAssets(), "fonts/OpenSans-Bold.ttf");
final Typeface italic = Typeface.createFromAsset(getAssets(), "fonts/OpenSans-Italic.ttf");
final Typeface boldItalic = Typeface.createFromAsset(getAssets(), "fonts/OpenSans-BoldItalic.ttf");
final Typeface regular = Typeface.createFromAsset(getAssets(),"fonts/OpenSans-Regular.ttf");
Field DEFAULT = Typeface.class.getDeclaredField("DEFAULT");
DEFAULT.setAccessible(true);
DEFAULT.set(null, regular);
Field DEFAULT_BOLD = Typeface.class.getDeclaredField("DEFAULT_BOLD");
DEFAULT_BOLD.setAccessible(true);
DEFAULT_BOLD.set(null, bold);
Field sDefaults = Typeface.class.getDeclaredField("sDefaults");
sDefaults.setAccessible(true);
sDefaults.set(null, new Typeface[]{
regular, bold, italic, boldItalic
});
} catch (NoSuchFieldException e) {
// logFontError(e);
} catch (IllegalAccessException e) {
// logFontError(e);
} catch (Throwable e) {
//cannot crash app if there is a failure with overriding the default font!
// logFontError(e);
}
}
来自Appstore的StackTrace:

我应该采取什么方法来解决这个问题?
最佳答案
我也从具有相同stacktrace的Lollipop设备中看到了这一点,也没有引用自己的代码。似乎是由于不完整的应用程序更新引起的平台错误,请参见https://code.google.com/p/android/issues/detail?id=56296
关于android - 尝试在空对象引用上调用虚拟方法 'android.content.res.AssetManager android.content.res.Resources.getAssets()',我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/30216635/
