我有一个问题是我的应用程序一直在崩溃我想要做的动画。它在我的Razr版本4.1.2上运行正常，但在星系上它与NumberFormatException崩溃，它的版本为2.3.6。
任何人都可以告诉我为什么会崩溃吗？我仍在试图弄清楚这是否是一个sdk版本问题。此外，我试图在三星S3上安装我签名的.apk，它甚至不会安装。它只是给我一个空白的屏幕。这似乎只是三星手机的一个问题。
public class RSEanimation extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setContentView(R.layout.startup);
final ImageView animationTarget1 = (ImageView) this.findViewById(R.id.rseImage);
final TextView animationTarget2 = (TextView) this.findViewById(R.id.textView1);
final TextView animationTarget3 = (TextView) this.findViewById(R.id.textView2);

答案 0 :(得分：3)
问题在于%元素scale.xml文件中的scale符号。那些不是必需的，因为这些属性的值需要是float，而不是string。
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_interpolator">
<rotate
android:toDegrees="720"
android:duration="2000"
android:pivotX="50%"
android:pivotY="50%"/>
<scale
android:fromXScale="0.1"
android:toXScale="100"
android:fromYScale="0.1"
android:toYScale="100"
android:duration="2000"
android:startOffset="100"/>
</set>
