公司的手机最近也开始进行CTS测试了。分配了几个ｂｕｇ给我，改的我欲仙欲死。 １:run cts -m CtsViewTestCases -t android.view.cts.PixelCopyTest#testWindowProducerCopyToRGBA16F 错误原因:未知 解决方案：修改以下文件 frameworks/base/libs/hwui/Extensions.cpp
＋mHasRenderableFloatTexture = extensions.has("GL_OES_texture_half_float");frameworks/base/libs/hwui/Extensions.h
+ inline bool hasRenderableFloatTextures() const { + return (mVersionMajor >= 3 && mVersionMinor >= 2) || mHasRenderableFloatTexture; + } + bool mHasRenderableFloatTexture;＋ bool mHasRenderableFloatTexture;
- if (bitmap->colorType() == kRGBA_F16_SkColorType && !caches.extensions().hasFloatTextures()) { + if (bitmap->colorType() == kRGBA_F16_SkColorType && + !caches.extensions().hasRenderableFloatTextures()) { ALOGW("Can't copy surface into bitmap, RGBA_F16 config is not supported"); return CopyResult::DestinationInvalid; }请看清楚加减号哦 ２:run cts -m CtsViewTestCases -t android.view.cts.ViewTest#testSetBackgroundResource 首先看报错ｌｏｇ。
java.lang.AssertionError: expected null, but was:<android.graphics.drawable.BitmapDrawable@7ebc70a> at org.junit.Assert.fail(Assert.java:88) at org.junit.Assert.failNotNull(Assert.java:755) at org.junit.Assert.assertNull(Assert.java:737) at org.junit.Assert.assertNull(Assert.java:747) at android.view.cts.ViewTest.testSetBackgroundResource(ViewTest.java:674) at java.lang.reflect.Method.invoke(Native Method) at org.junit.runners.model.FrameworkMethod$1.runReflectiveCall(FrameworkMethod.java:50) at org.junit.internal.runners.model.ReflectiveCallable.run(ReflectiveCallable.java:12) at org.junit.runners.model.FrameworkMethod.invokeExplosively(FrameworkMethod.java:47) at org.junit.internal.runners.statements.InvokeMethod.evaluate(InvokeMethod.java:17) at org.junit.internal.runners.statements.FailOnTimeout$CallableStatement.call(FailOnTimeout.java:148) at org.junit.internal.runners.statements.FailOnTimeout$CallableStatement.call(FailOnTimeout.java:145) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.lang.Thread.run(Thread.java:764)可以看到是viewTest的674行，继续追踪
@Test public void testSetBackgroundResource() { View view = new View(mActivity); assertNull(view.getBackground()); view.setBackgroundResource(R.drawable.pass); assertNotNull(view.getBackground()); view.setBackgroundResource(0); assertNull(view.getBackground()); }可以看到最后两句代码他把view的背景设置为空进行断言判断，却发现view的背景并不为空，所以导致本项测试fail。也就是说view.setBackgroundResource为空失败。那么我们进入view源码里面看看。果不其然发现同事在其中加了个判断。修改下就能Pass了
int if_auto_switch_wallpaper=android.provider.Settings.System.getInt(mContext.getContentResolver(),"AUTO_SWITCH_WALLPAPER",1); if(resid==0&&if_auto_switch_wallpaper==1){ return; }3:run cts -m CtsShortcutManagerTestCases -m android.content.pm.cts.shortcutmanager.ShortcutManagerClientApiTest#testShortcutInfoMissingMandatoryFields 找了我n久，最后问了mtk才知道是豁免项，百度竟然没有。心痛。 Google bug id : 112251274 ４:run cts -m CtsSecurityTestCases -t android.security.cts.PackageSignatureTest#testPackageSignatures 这个百度倒是挺多的,原因是因为使用了谷歌默认的key,需要自己生成key替换掉。 具体解决方法: 第一步：生成自定义的key,进入/android_src/development/tools目录。使用目录下的make_key工具。
development/tools$ sh make_key releasekey '/C=CN/ST=JiangSu/L=NanJing/O=Company/OU=Department/CN=YourName/emailAddress=YourE-mailAddress' Enter password for 'releasekey' (blank for none; password will be visible): mypassword <------- 设置你的密码 creating platform.pk8 with password [mypassword] Generating RSA private key, 2048 bit long modulus这是我百度到的一段代码。说实话，把我坑的够惨，不管怎么样设置密码为空都成功不了。博主也未说明。找了半天才知道这是本来就有的坑。需要换一种方式写法才行，直接用./，而不是sh make_key
./make_key '/C=CN/ST=GuangDong/L=ShenZhen/O=Forme/OU=Development/CN=Forme/emailAddress=13510507054@163.com' releasekey C ---> Country Name (2 letter code) ST ---> State or Province Name (full name) L ---> Locality Name (eg, city) O ---> Organization Name (eg, company) OU ---> Organizational Unit Name (eg, section) CN ---> Common Name (eg, your name or your server’s hostname) emailAddress ---> Contact email address请一定要注意生成key的时候设置密码为空。make编译的时候是不会给你输密码的。会报错的。而且需要生成releasekey，media，shared，platform，都是需要的， 第二部：把生成的8个文件替换掉默认key，路径:项目名/build/make/target/product/security 第三部：更改项目配置。build/make/core/Makefile，在BUILD_KEYS := test-keys下添加以下语句。
BUILD_KEYS := test-keys endif ifeq ($(DEFAULT_SYSTEM_DEV_CERTIFICATE),build/target/product/security/releasekey) BUILD_KEYS := release-keys路径：device/mediatek/common/device.mk添加以下语句。
PRODUCT_DEFAULT_DEV_CERTIFICATE := build/target/product/security/releasekey然后重新编译一次就行就可以pass这个测试了。
５：run cts -m CtsSystemUiTestCases -t android.systemui.cts.LightBarTests#testLightStatusBarIcons 原因：未知 测试过程中发现systemui里面有个变量报空。按道理来说应该是不可能报空的，因为我们没有修改过那里，不知道是怎么回事。给那个变量加个为空判断就ＰＡＳＳ了
--- a/vendor/mediatek/proprietary/packages/apps/SystemUI/src/com/android/systemui/statusbar/phone/LightBarController.java +++ b/vendor/mediatek/proprietary/packages/apps/SystemUI/src/com/android/systemui/statusbar/phone/LightBarController.java @@ -265,7 +265,8 @@ public class LightBarController implements BatteryController.BatteryStateChangeC mStatusBarIconController.getTransitionsController().dump(fd, pw, args); pw.println(); pw.println(" NavigationBarTransitionsController:"); - mNavigationBarController.dump(fd, pw, args); + if(mNavigationBarController!=null){mNavigationBarController.dump(fd, pw, args);} + pw.println(); } }嘛。暂时就这些。如有不对，请多指教。
