Android Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0 in tid 29092
提问by hashcode55
I'm try to play a loading animation on my loading screen, and I read somewhere that android doesn't support gifs so either you have to break in into frames and then play it or we can use the Movie class.
我试图在我的加载屏幕上播放加载动画，我在某处读到 android 不支持 gif，所以要么你必须插入帧然后播放它，要么我们可以使用 Movie 类。
Heres the leading activity -
这是主要活动 -

}
}).setNegativeButton("I'll fkin face it",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
}
});
AlertDialog alert = builder.create();
alert.show();
}
}
In the above code I've set content view by passing it an instance of MYGIFView.class -
在上面的代码中，我通过传递一个 MYGIFView.class 的实例来设置内容视图 -
Heres MYGIFView.class
继承人 MYGIFView.class
package com.myapp.mehul.login;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Movie;
import android.view.View;
import java.io.InputStream;
/**
* Created by mehul on 2/7/16.
*/
public class MYGIFView extends View{
Movie movie,movie1;
InputStream is=null,is1=null;
long moviestart;
public MYGIFView(Context context) {
super(context);
is=context.getResources().openRawResource(+ R.drawable.loading);
movie=Movie.decodeStream(is);
}
@Override
protected void onDraw(Canvas canvas) {
canvas.drawColor(Color.WHITE);
super.onDraw(canvas);
long now=android.os.SystemClock.uptimeMillis();
System.out.println("now="+now);
if (moviestart == 0) { // first time
moviestart = now;
}
System.out.println("\tmoviestart="+moviestart);
int relTime = (int)((now - moviestart) % movie.duration()) ;
System.out.println("time="+relTime+"\treltime="+movie.duration());
movie.setTime(relTime);
movie.draw(canvas,this.getWidth()/2-20,this.getHeight()/2-40);
this.invalidate();
}
}
The loading activity IS creating an instance of MYGIFView.class and it logs the data but then it gives fatal signal 11. I tried to search but I didn't get any answer.
加载活动正在创建 MYGIFView.class 的一个实例，它记录数据，但随后给出致命信号 11。我尝试搜索，但没有得到任何答案。

I received a batch for this question which means its being viewed a lot, so I'll answer this question -
我收到了这个问题的一批，这意味着它被查看了很多，所以我来回答这个问题 -
What I figured out was the line below was throwing the error -
我发现下面的行抛出了错误 -
movie.draw(canvas,this.getWidth()/2-20,this.getHeight()/2-40);
Now the problem is that this error specifically can be caused by lots of reasons, its never a specific reason.. the reason mine wasn't working out was because my device didn't work well with hardware acceleration, so I just had to disable it in the manifest application, like this -
现在的问题是，这个错误可能是由很多原因引起的，它从来都不是一个特定的原因。它在清单应用程序中，像这样 -
<android:hardwareAccelerated="false">
Now its possible that the reason might not be the same....but the core reason is the same, its memory related, and most chances are its a bug in the firmware of the device or emulator you are testing upon.
现在可能原因可能不一样......但核心原因是相同的，它的内存相关，并且最有可能是您正在测试的设备或模拟器的固件中的错误。

In the Manifest set in your activity :
在您的活动中的清单集中：
<activity
android:name="LoadingScreen"
android:hardwareAccelerated="false">
</activity>
