本文主要是介绍android系统使用Camera2 应用，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
系统默认的配置是Camera2应用没有显示在桌面的根据freescaleandroid5.1/packages/apps/Camera2/Android.mk文件内容
ifeq ($(HAVE_FSL_IMX_GPU3D),true)ifeq ($(BOARD_HAVE_VPU),true)LOCAL_PATH:= $(call my-dir)include $(CLEAR_VARS)LOCAL_MODULE_TAGS := optionalLOCAL_STATIC_JAVA_LIBRARIES := android-support-v13LOCAL_STATIC_JAVA_LIBRARIES += android-ex-camera2-portabilityLOCAL_STATIC_JAVA_LIBRARIES += xmp_toolkitLOCAL_STATIC_JAVA_LIBRARIES += glideLOCAL_SRC_FILES := $(call all-java-files-under, src)LOCAL_SRC_FILES += $(call all-java-files-under, src_pd)LOCAL_SRC_FILES += $(call all-java-files-under, src_pd_gcam)LOCAL_RESOURCE_DIR += \$(LOCAL_PATH)/res \$(LOCAL_PATH)/res_pinclude $(LOCAL_PATH)/version.mkLOCAL_AAPT_FLAGS := \--auto-add-overlay \--version-name "$(version_name_package)" \--version-code $(version_code_package) \LOCAL_PACKAGE_NAME := Camera2LOCAL_SDK_VERSION := currentLOCAL_PROGUARD_FLAG_FILES := proguard.flagsLOCAL_JNI_SHARED_LIBRARIES := libjni_tinyplanet libjni_jpegutilinclude $(BUILD_PACKAGE)include $(call all-makefiles-under, $(LOCAL_PATH))endifendif需要时能HAVE_FSL_IMX_GPU3D和BOARD_HAVE_VPU
所以，在freescaleandroid5.1/device/fsl/sabresd_6dq/BoardConfig.mk文件中添加如下配置
# add for carmera2HAVE_FSL_IMX_GPU3D := trueBOARD_HAVE_VPU := true
删掉freescaleandroid5.1/out/target/product/sabresd_6dq/system/app/Camera2文件夹；重新编译，替换卡中的uramdisk.img文件即可
这篇关于android系统使用Camera2 应用的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
