1: svn出错
svn: E200033: Another process is blocking the working copy database, or the underlying filesystem does not support file locking; if the working copy is on a network filesystem, make sure file locking has been enabled on the file server
svn: E200033: sqlite[S5]: database is locked
svn: E200042: Additional errors:
svn: E200033: sqlite[S5]: database is locked
执行：
cd /your project/.svn
mv wc.db wc.db.old
sqlite3 wc.db.old

2. INSTALL_FAILED_UPDATE_INCOMPATIBLE（更新不兼容）（adb）
解决：
（1）、卸载掉之前的程序，再安装
（2）、如果第一步还是不行，adb uninstall 程序的包名、再adb install ...

一般是缺少平板的配置：加上：
implementation 'com.android.support:appcompat-v7:26.0.0'
implementation 'com.android.support:customtabs:26.0.0'
4.自2019年8月1日起， 在Google Play中发布应用都必须提供64位版本
1.使用 Android Studio 或 Gradle 进行编译
修改如下：
大多数 Android Studio 项目都使用 Gradle 作为底层编译系统，因此本部分适用于使用这两种工具进行编译的情况。针对原生代码进行编译很简单，只需将 arm64-v8a 和/或 x86_64（取决于您要支持的架构）添加到应用的“build.gradle”文件中的 ndk.abiFilters 设置：
// Your app's build.gradle
apply plugin: 'com.android.app'
android {
compileSdkVersion 27
defaultConfig {
appId "com.google.example.64bit"
minSdkVersion 15
targetSdkVersion 28
versionCode 1
versionName "1.0"
ndk.abiFilters 'armeabi-v7a','arm64-v8a','x86','x86_64'
// ...
2.使用 ndk-build 进行编译
如果您的应用是使用 ndk-build 编译的，则可以通过 APP_ABI 变量修改“app.mk”文件，从而编译 64 位 ABI：
APP_ABI := armeabi-v7a arm64-v8a x86 x86_64

5.android-studio编译错误->计费点问题
error:
Failed to query inventory:labResult:Error refreshing inventory(Querying owned items).Failed to query inventory:labResult:Error refreshing inventory(Querying owned items).response:-1003: Purchase signature verification failed
这个错提示：
查询库存出错，
原因是我们换了开发者账号，并重新设置计费点， 但是并没有换，验证公钥， 所以回报这个错/
