Android O CTS 测试之Media相关测试小结（二）

CtsMediaTestCases

android.media.cts.VideoDecoderPerfTest failed

failed 项：android.media.cts.VideoDecoderPerfTest#testHevcGoog0Perf1280x0720 fail

failed information：junit.framework.AssertionFailedError: Expected achievable frame rates for OMX.google.hevc.decoder video/hevc 1280x720: [27.0, 27.0].

failed 项：android.media.cts.VideoDecoderPerfTest#testHevcGoog0Perf1920x1080 fail

failed information：junit.framework.AssertionFailedError: Expected achievable frame rates for OMX.google.hevc.decoder video/hevc 1920x1080: [11.0, 11.0].

对于此类failed项需要多跑几次failed case，找到合适的codec performance limit 的范围.在测试的log中可以找到当时测试时的值

相应的文件media_codecs_performance.xml在android的system/vendor/etc目录下

项目代码中的路径是：

isNotificationPolicyAccessGranted())返回了false与期望不符合；

protected static void toggleNotificationPolicyAccess(String packageName,
Instrumentation instrumentation, boolean on) throws IOException {
......
NotificationManager nm = (NotificationManager) instrumentation.getContext()
.getSystemService(Context.NOTIFICATION_SERVICE);
Assert.assertEquals("Wrote setting should be the same as the read one", on,
nm.isNotificationPolicyAccessGranted());
}

查看：isNotificationPolicyAccessGranted

最终发现：

private boolean checkPolicyAccess(String pkg) {
2582              try {
2583                  int uid = getContext().getPackageManager().getPackageUidAsUser(
2584                          pkg, UserHandle.getCallingUserId());
2585                  if (PackageManager.PERMISSION_GRANTED == ActivityManager.checkComponentPermission(
2586                          android.Manifest.permission.MANAGE_NOTIFICATIONS, uid,
2587                          -1, true)) {
2588                      return true;
2589                  }
2590              } catch (NameNotFoundException e) {
2591                  return false;
2592              }
2593              return checkPackagePolicyAccess(pkg) || mListeners.isComponentEnabledForPackage(pkg);
2594          }

cts media测试没有android.Manifest.permission.MANAGE_NOTIFICATIONS的权限

最终确认是已知的google issue，向Google申请豁免

同样还有如下类似的failed项

failed项：

android.media.cts.AudioManagerTest#testAdjustVolumeInAlarmsOnlyMode fail

android.media.cts.AudioManagerTest#testAdjustVolumeInTotalSilenceMode fail

android.media.cts.AudioManagerTest#testSetStreamVolumeInAlarmsOnlyMode fail

android.media.cts.AudioManagerTest#testSetStreamVolumeInTotalSilenceMode fail
