由 会有一股神秘感。 提交于 2020-01-19 13:37:07
问题 .NET assemblies that contain a mixture of managed and unmanaged code cannot be ILMerged with other assemblies. How can I verify if a given .NET assembly contains purely managed code, or a mix of managed and unmanaged code? 回答1: Run the PEVerify tool against your assembly. PEVerify.exe is installed along with Visual Studio, e.g. this one comes with Visual Studio 2012: C:\Program Files (x86)\Microsoft SDKs\Windows\v8.0A\bin\NETFX 4.0 Tools\PEVerify.exe 回答2: As suggested by nobugz, an easier way

问题 I have a simple Android Hybrid and Native Application developed using Worklight 6.0. Over http both the apps work fine with connecting to the server and invoking a procedure. But as soon as I move to https, hybrid app works fine, but I can see that the native connect request itself is not received at the server end.

是否需要主动调用Bitmap的recycle方法

由 拈花ヽ惹草 提交于 2020-01-15 23:02:17
一个Bitmap使用完后，是只需要等它成为垃圾后让GC去回收，还是应该主动调用recycle方法呢？或者说，主动调用recycle方法是否有好处，是否能马上回收内存呢？ 带着这个问题来看源码（我看的4.4源码）。 先看Bitmap内存的创建，通过跟踪Bitmap.createBitmap方法，可以发现是native方法里调用的JVM来创建的： jbyteArray arrayObj = env->NewByteArray(size); native使用的是通过其得到的一个固定地址： jbyte* addr = jniGetNonMovableArrayElements(&env->functions, arrayObj); native里会用一个SkPixelRef来存放他们： SkPixelRef* pr = new AndroidPixelRef(env, bitmapInfo, (void*) addr, bitmap->rowBytes(), arrayObj, ctable); 然后将这个传给Bitmap： bitmap->setPixelRef(pr); 再看recycle过程： java端： mBuffer = null; native端： Caches::getInstance().textureCache.removeDeferred(bitmap);

Native Flash on mobile platforms?

问题 Does anyone know if Flash will be able to run independent from the browser? I mean native apps in Flash , not just the player in a browser. The Symbian OS can do that, however I have yet to find an article which explicitly states what will become available in the case of the iPhone and the Android platform. I am not asking about dates, as those are the most fluctuation prone variables. I am part of a web/mobile apps development company which is eager to use flash to make applications even

问题 I am working on a React Native application that authenticates requests with JWT tokens.
