testMediaMatrix.put(H264, Arrays.asList( createMediaItem(480p_h264_aac.mp4), createMediaItem(1080p_h264_aac.mp4) )); testMediaMatrix.put(H265, Arrays.asList( createMediaItem(720p_hevc_aac.mp4) ));关键技术实现方案设备能力探测与适配在测试开始前需要检测设备硬件能力动态调整测试策略public class DeviceCapabilityDetector { public static boolean supportsHevc() { MediaCodecList codecList new MediaCodecList(MediaCodecList.ALL_CODECS); for (MediaCodecInfo codecInfo : codecList.getCodecInfos()) { if (codecInfo.isEncoder()) continue; for (String type : codecInfo.getSupportedTypes()) { if (type.equalsIgnoreCase(video/hevc)) { return true; } } } return false; } public static boolean isLowEndDevice() { ActivityManager activityManager (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE); ActivityManager.MemoryInfo memoryInfo new ActivityManager.MemoryInfo(); activityManager.getMemoryInfo(memoryInfo); return memoryInfo.totalMem 2L * 1024 * 1024 * 1024; // 小于2GB内存 } }自动化测试脚本设计利用Espresso和UI Automator创建自动化测试脚本覆盖关键播放场景RunWith(AndroidJUnit4.class) public class ExoPlayerCompatibilityTest { Test public void testVideoPlaybackOnDifferentResolutions() { // 测试不同分辨率视频播放 ListResolution resolutions Arrays.asList( new Resolution(480, 854), new Resolution(720, 1280), new Resolution(1080, 1920), new Resolution(1440, 2560) ); for (Resolution res : resolutions) { MediaItem mediaItem createTestMedia(res.width, res.height); player.setMediaItem(mediaItem); player.prepare(); // 验证播放状态 onView(withId(R.id.player_view)) .check(matches(isDisplayed())); // 验证播放进度 assertThat(player.getPlaybackState()) .isEqualTo(Player.STATE_READY); } } Test public void testNetworkAdaptivePlayback() { // 模拟不同网络条件下的自适应播放 NetworkCondition[] conditions { new NetworkCondition(WiFi, 50_000_000), // 50Mbps new NetworkCondition(4G, 10_000_000), // 10Mbps new NetworkCondition(3G, 1_000_000), // 1Mbps new NetworkCondition(2G, 100_000) // 100Kbps }; for (NetworkCondition condition : conditions) { simulateNetworkCondition(condition); testDashStreamingAdaptation(); } } }ExoPlayer自定义UI布局示例展示如何通过覆盖布局文件实现个性化播放器界面这是UI兼容性测试的重要方面自动化测试与持续集成CI/CD流水线配置将兼容性测试集成到持续集成流程中确保每次代码变更都经过验证# .github/workflows/exoplayer-compatibility.yml name: ExoPlayer Compatibility Test on: [push, pull_request] jobs: compatibility-test: runs-on: ubuntu-latest strategy: matrix: api-level: [24, 28, 30, 33] steps: - uses: actions/checkoutv3 - name: Set up JDK 17 uses: actions/setup-javav3 with: java-version: 17 distribution: temurin - name: Run compatibility tests run: | ./gradlew connectedCheck \ -Pandroid.testInstrumentationRunnerArguments.class\ com.google.android.exoplayer2.playbacktests.gts.DashStreamingTest - name: Upload test results uses: actions/upload-artifactv3 with: name: test-results-api-${{ matrix.api-level }} path: library/**/build/reports/androidTests/connected/设备云测试集成利用云测试服务扩展设备覆盖范围public class FirebaseTestLabIntegration { public void runCompatibilityTestSuite() { // 配置Firebase Test Lab测试矩阵 TestMatrix testMatrix new TestMatrix() .setTestSpecification(createTestSpecification()) .setEnvironmentMatrix(createEnvironmentMatrix()) .setResultStorage(createResultStorage());
