Android学习笔记--GMS认证（常见的cts—fail及解决方法）
GMS认证
一、lunch桌面的google应用排序要求：
Google apps folder should contain applications in the following order from left to right; top to bottom.Google Chrome, Gmail, Google+, Google Maps, Google Play Music, Google Play Movies, Google Play Books, Google Play Newsstand, Google Play Games, Google Drive, YouTube, Google Plus Photos, Hangouts
二、 测试命令
1）全量测试:
run cts –plan CTS
2) fail项测试：
l r
run cts –continue-session session ID
3）单测试某个case:
a．run cts -c class name -m case name
比如：run cts -c android.hardware.cts.CameraGLTest -m testCameraToSurfaceTextureMetadata
b. run cts -t class name#case name ,
如：run cts -t android.hardware.cts.CameraGLTest#testCameraToSurfaceTextureMetadata
4）测试一个包：
a. run cts -c class name; 比如：run cts -c android.hardware.cts.CameraGLTest
b. run cts -p class name,
比如： start --plan CTS -p android.hardware.cts.CameraGLTest
5）fail项测试：
add derivedplan -r fail -s 0 -p xie//导出fail项
run cts --plan xie//测试fail项
三、 CTS_fail总结
1）android.view.accessibility.cts.AccessibilityManagerTest
-- testAddAndRemoveAccessibilityStateChangeListener fail junit.framework.AssertionFailedError: Accessibility should have been enabled by the test runner. expected:<1> but was:<0> at junit.framework.Assert.fail(Assert.java:50)
-- testGetAccessibilityServiceList fail junit.framework.AssertionFailedError: Accessibility should have been enabled by the test runner. expected:<1> but was:<0> at junit.framework.Assert.fail(Assert.java:50)
-- testGetEnabledAccessibilityServiceList fail junit.framework.AssertionFailedError: Accessibility should have been enabled by the test runner. expected:<1> but was:<0> at junit.framework.Assert.fail(Assert.java:50)
-- testGetEnabledAccessibilityServiceListForType fail junit.framework.AssertionFailedError: Accessibility should have been enabled by the test runner. expected:<1> but was:<0> at junit.framework.Assert.fail(Assert.java:50)
-- testGetInstalledAccessibilityServicesList fail junit.framework.AssertionFailedError: Accessibility should have been enabled by the test runner. expected:<1> but was:<0> at junit.framework.Assert.fail(Assert.java:50)
-- testInterrupt fail junit.framework.AssertionFailedError: Accessibility should have been enabled by the test runner. expected:<1> but was:<0> at junit.framework.Assert.fail(Assert.java:50)
-- testIsTouchExplorationEnabled fail junit.framework.AssertionFailedError: Accessibility should have been enabled by the test runner. expected:<1> but was:<0> at junit.framework.Assert.fail(Assert.java:50)
-- testSendAccessibilityEvent fail junit.framework.AssertionFailedError: Accessibility should have been enabled by the test runner. expected:<1> but was:<0> at junit.framework.Assert.fail(Assert.java:50)
-- testAndroidTestCaseSetupProperly fail junit.framework.AssertionFailedError: Accessibility should have been enabled by the test runner. expected:<1> but was:<0> at junit.framework.Assert.fail(Assert.java:50)
android.view.accessibility.cts.AccessibilityServiceInfoTest
-- testAccessibilityServiceInfoForEnabledService fail junit.framework.AssertionFailedError: There should be one speaking service. expected same:<1> was not:<0> at junit.framework.Assert.fail(Assert.java:50)
首先确认手机是否是低内存的，如果是请关闭内存优化：
修改： ProjectConfig.mk
修改记录：-CONFIG_LOWMEMORY = yes
+CONFIG_LOWMEMORY = no
2）testBatchScan
android.bluetooth.cts.BluetoothLeScanTest
-- testBatchScan fail junit.framework.AssertionFailedError at junit.framework.Assert.fail(Assert.java:48)
-- testOpportunisticScan fail junit.framework.AssertionFailedError: Scan results shouldn't be empty at junit.framework.Assert.fail(Assert.java:50)
-- testScanFilter fail junit.framework.AssertionFailedError: Scan results shouldn't be empty at junit.framework.Assert.fail(Assert.java:50)
该项测试是测试bluetooth的需要测试环境要包含三个或者三个以上的BLE设备，一般也可以安装apk来模拟BLE设备。
3）test4_1MeasurePeakRms
android.media.cts.VisualizerTest
-- test4_1MeasurePeakRms fail junit.framework.AssertionFailedError: peak deviation in mB=2797 at junit.framework.Assert.fail(Assert.java:50)
-- test4_2MeasurePeakRmsLongMP3 fail junit.framework.AssertionFailedError: peak deviation in mB=2813 at junit.framework.Assert.fail(Assert.java:50)
关闭besloundness再测试，这个菜单位于Settings/sound¬ification/sound enhancement ，默认是开启的。
Note:
xxxxx的DRC(BesLoudness)会在AudioEffect之前处理。该CTS测试项会在AudioEffect中取出data并计算PeakRms。由于DRC会对gain值产生影响，而CTS测试对gain值有所限制，所以BES_LOUDNESS_MUSICDRC_SB_GAIN会影响最终CTS测试的结果。
4）testLiveWallpaperFeature
android.app.cts.SystemFeaturesTest
-- testLiveWallpaperFeature fail junit.framework.AssertionFailedError: PackageManager#hasSystemFeature should return true for android.software.live_wallpaper at junit.framework.Assert.fail(Assert.java:50)
从问题上可以看出是需要判定需要设置 android.software.live_wallpaper为真，修改：
packages/wallpapers/LivePicker/ android.software.live_wallpaper.xml文件修改为真。
5）testCameraFeatures
android.app.cts.SystemFeaturesTest
-- testCameraFeatures fail junit.framework.AssertionFailedError: PackageManager#hasSystemFeature should NOT return true for android.hardware.camera.autofocus at junit.framework.Assert.fail(Assert.java:50)
修改路径： android.hardware.camera.xml:
<！--feature name="android.hardware.camera.autofocus" /-->
6）testBurstVideoSnapshot
-- testBurstVideoSnapshot fail com.android.ex.camera2.exceptions.TimeoutRuntimeException: Timed out after 3000 ms waiting for state(s) SESSION_CLOSED at com.android.ex.camera2.utils.StateWaiter.waitForAnyOfStates(StateWaiter.java:164)
-- testVideoSnapshot fail junit.framework.AssertionFailedError: Wait for a capture result timed out in 3000ms at junit.framework.Assert.fail(Assert.java:50)
一般是由于光照等原因导致的，打灯进行重新测试。
要求：
1 亮度要求：后摄：不要将平板直接放在桌子上进行测试，后摄被遮挡，一般后摄的fps因为外部光源较弱就会被降低，最好放在支架上，后摄可以对着明亮的电脑屏幕或者灯光；
前摄： 不要在平板上前摄盖着东西，或者因为全测时间很长，在夜晚关闭灯光放在黑暗环境下去测试，这样前摄的fps也很可能被降低,摄最好也对着灯光。
明亮环境： 可以打开camera，在main log中搜索aaa_state_camera_preview: lv, 此值一般要在60以上。
2 帧率要求：最好preview,capture都可以达到30fps, 建议preview的帧率至少在24fps以上，capture的帧率在15fps以上。
3 Driver部分：
1 ）理论fps值：此方面需要和sensor FAE或者datasheet确定设置寄存器的代码，确定sensor输出的理论fps值。
2 ） 提高driver性能：
减少延时： camera sensor driver减少上电延时和driver init/preview/capture/setting/feature control等的延时：
尽可能在符合camera sensor spec的基础上减少延时；
camera sensor driver I2C speed提高：
默认的I2C speed应该是100K, 如果camera sensor可支持，可以尝试提高到400K来测试，这样camera driver中读写I2C的速度会提高到之前的4倍；
camera driver在不影响画面显示的情况下尽可能减少delay frame:
如下的数值尽可能减少：
.cap_delay_frame = 3,
.pre_delay_frame = 3,
.video_delay_frame = 3,
实际中，可以先都改为0来测试cts是否可以pass, 如果可以pass, 再查看camera preview/capture/video开始显示画面时是否有黑屏/绿屏/杂线的问题，如果有，可以酌情。

7） testOctane
-- testOctane fail Test failed to run to completion. Reason: 'Instrumentation run failed due to 'junit.framework.AssertionFailedError''. Check device logcat for details
设置默认浏览器为chrome
8） testOwnerChangedBroadcast
com.android.cts.devicepolicy.CustomDeviceOwnerTest
-- testOwnerChangedBroadcast fail junit.framework.AssertionFailedError at junit.framework.Assert.fail(Assert.java:48)
com.android.cts.devicepolicy.LauncherAppsSingleUserTest

-- testLauncherCallbackPackageRemovedMainUser fail junit.framework.AssertionFailedError at junit.framework.Assert.fail(Assert.java:48)
修改：ProjectConfig.mk（关闭低内存的内存优化）
修改记录：-CONFIG_LOWMEMORY = yes
+CONFIG_LOWMEMORY = no
