處理方法：

1. 延時啓動監聽器;
2. 不要監聽;

Android 6.0上新的機制，系統語言默認會先從SIM卡里讀取，通過卡的里語言來匹配。

如果不想讓系統語言隨卡里的語言匹配，可以將frameworks\base\core\res\res\values\Config.xml下的config_use_sim_language_file配置爲false即可。

還有一種是通過網絡來改變系統語言，如果也不想使用此功能，可以將frameworks/opt/telephony/src/java/com/android/internal/telephony/MccTable.java裏updateMccMncConfiguration方法中的setWifiCountryCodeFromMcc調用方案註釋掉即可。

修改如下：

APK放入system內，並且加入so庫;

overrides/mediatek/packages/apps/haoxuexi
同目錄下創建 lib文件夾 + haoxuexi.apk +Android.mk

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)

LOCAL_MODULE_TAGS := optional

LOCAL_SRC_FILES := $(LOCAL_MODULE).apk

${warning $(TARGET_OUT)==================liecen mkdir===================================}
$(shell mkdir -p $(TARGET_OUT)/lib/)
$(shell cp -r $(LOCAL_PATH)/lib/* $(TARGET_OUT)/lib/)
include $(BUILD_PREBUILT)

build/target/product/core.mk文件也需要加入包名

---

apk使用系統簽名：

簽名:
使用android自帶的簽名工具signapk.jar 以及源碼中的platform.x509.pem,platform.pk8　對apk進行重新簽名。

  　執行：java -jar signapk.jar  platform.x509.pem platform.pk8　old.apk new.apk　執行後new.apk即爲簽名後的文件。

　　 (注：執行命令時所有文件這裏放在同一目錄下，如果不在同一目錄請修改路徑)。

　　文件platform.x509.pem和platform.pk8我們可以在源碼的　build/target/product/security中找到。signapk.jar 可以編譯build/tools/signapk/ 得到。

5.簽名後就可以安裝使用了

另外這樣簽名後可能會導致不能操作sdcard目錄下的文件。

關閉指紋識別解鎖

Update Notes:
== [email protected] On 20180810T08:01:42 (xml) ==
關於com.sprd.applock.AppLockApplication has stoped問題，請按照如下修改：
vendor/sprd/platform/packages/apps/AppSecurity/ApplicationLock/src/com/sprd/launchapp/LaunchAppService.java：

} else if (action.equals(Intent.ACTION_PACKAGE_REMOVED)) {
String packageName = intent.getData().getSchemeSpecificPart();
FingerprintManager fingerprintManager = (FingerprintManager) mContext.getSystemService(
Context.FINGERPRINT_SERVICE);
+++ if(fingerprintManager == null)
+++ return;
final List items = fingerprintManager.getEnrolledFingerprints();
//reset the launch application function

項目是否不支持指紋功能，ApplicationLock主要功能是指紋啓動應用和應用鎖，若是客戶不支持指紋，建議將這個應用去掉：
去掉這個應用的方式爲刪掉device/sprd/pike2/common/security_feature.mk文件中的如下代碼：

enable Fingerprint feature

PRODUCT_PROPERTY_OVERRIDES += \
persist.support.fingerprint=true \
persist.sprd.fp.lockapp=true \
persist.sprd.fp.launchapp=true

for fingerprint lockapp\launchapp function

PRODUCT_PACKAGES += ApplicationLock
BOARD_SEPOLICY_DIRS += vendor/sprd/platform/packages/apps/AppSecurity/ApplicationLock/sepolicy
