问题1.io.reactivex.exceptions.UndeliverableException:The exception could not be delivered to the consumer because it has already canceled/disposed the flow or the exception has nowhere to go to begin with. Further reading: https://github.com/ReactiveX/RxJava/wiki/What's-different-in-2.0#error-handling | java.lang.Throwable: Unable to resolve host "upload-fs.qiniup.com": No address associated with hostname
io.reactivex.plugins.RxJavaPlugins.onError(RxJavaPlugins.java:367)
解决：在自定义Application的onCreate()调用setRxJavaErrorHandler()
private void setRxJavaErrorHandler() {
if (RxJavaPlugins.getErrorHandler() != null || RxJavaPlugins.isLockdown()) {
LogUtils.d("App", "setRxJavaErrorHandler getErrorHandler()!=null||isLockdown()");
return;
}
RxJavaPlugins.setErrorHandler(new Consumer
@Override
public void accept(Throwable e) {
if (e instanceof UndeliverableException) {
e = e.getCause();
LogUtils.d("App", "setRxJavaErrorHandler UndeliverableException=" + e);
return;
} else if ((e instanceof IOException)) {
// fine, irrelevant network problem or API that throws on cancellation
return;
} else if (e instanceof InterruptedException) {
// fine, some blocking code was interrupted by a dispose call
return;
} else if ((e instanceof NullPointerException) || (e instanceof IllegalArgumentException)) {
// that's likely a bug in the application
Thread.UncaughtExceptionHandler uncaughtExceptionHandler =
Thread.currentThread().getUncaughtExceptionHandler();
if (uncaughtExceptionHandler != null) {
uncaughtExceptionHandler.uncaughtException(Thread.currentThread(), e);
}
return;
} else if (e instanceof IllegalStateException) {
// that's a bug in RxJava or in a custom operator
Thread.UncaughtExceptionHandler uncaughtExceptionHandler =
Thread.currentThread().getUncaughtExceptionHandler();
if (uncaughtExceptionHandler != null) {
uncaughtExceptionHandler.uncaughtException(Thread.currentThread(), e);
}
return;
}
LogUtils.d("App", "setRxJavaErrorHandler unknown exception=" + e);
}
});
}
问题2:java.lang.IllegalArgumentException
You cannot start a load for a destroyed activity
解决： Glide调用之前判断activity是否销毁
//Fix You cannot start a load for a destroyed activity
if (activity == null
|| activity.isFinishing()
|| activity.isDestroyed()) {
return;
}
Glide.with(context).load(url).into(ImageView)
问题3：java.lang.ClassCastException android.graphics.drawable.AnimatedImageDrawable cannot be cast to android.graphics.drawable.BitmapDrawable
解决： 这个是CropImageView做裁剪界面时，未过滤gif导致
@Nullable
public Bitmap getCropBitmap(int expectWidth, int exceptHeight, boolean isSaveRectangle) {
if (expectWidth <= 0 || exceptHeight < 0) return null;
Drawable drawable = this.getDrawable();
if (drawable == null) return null;
if (drawable instanceof BitmapDrawable) {
Bitmap srcBitmap = ((BitmapDrawable) drawable).getBitmap();
srcBitmap = rotate(srcBitmap, sumRotateLevel * 90); //最好用level，因为角度可能不是90的整数
return makeCropBitmap(srcBitmap, mFocusRect, getImageMatrixRect(), expectWidth,
exceptHeight, isSaveRectangle);
}
return null;
}
问题4:遇到ImageView.setImageURI() 导致anr
解决： 使用glide加载
Glide.with(context)
.load(uri)
.apply(options)
.into(imageView);
问题5: java与Kotlin混用时注意int与Int
Java
public class Simple(){
private int type;
}
kotlin
data class Simple(val type: Int)
遇到
public class MyRecyclerViewAdapter extends RecyclerView.Adapter
...
@Override
public int getItemViewType(int position) {
//此种用法有时kotlin定义实体类会有问题，type判断不准
return datas.get(position).type;
}
}
解决： 使用到getItemViewType（int postion）方法时 编码都用java要么kotlin
