            if(data.type == "f" || data.type == "e"){
                $('.site-subtitle').html(data.hitokoto)
            }else{
                $('.site-subtitle').html(data.hitokoto + " - " + data.from)
            }
    })
})
</script>

这样会导致站点subtitle配置无效

            debuggable true
            signingConfig signingConfigs.release
        }

        debug {
            signingConfig signingConfigs.release
        }
    }

}

如果团队协作开发或者将代码开源，那么应当将此敏感信息从构建文件中移出，以免被其他人轻易获取。

1.在项目的根目录下创建一个名为 keystore.properties 的文件。

1
2
3
4
storePassword=myStorePassword
keyPassword=mykeyPassword
keyAlias=myKeyAlias
storeFile=myStoreFileLocation

2.在模块的 build.gradle 文件中，于 android {} 块的前面添加用于加载 keystore.properties 文件的代码

...

// Create a variable called keystorePropertiesFile, and initialize it to your
// keystore.properties file, in the rootProject folder.
def keystorePropertiesFile = rootProject.file("keystore.properties")

// Initialize a new Properties() object called keystoreProperties.
def keystoreProperties = new Properties()

// Load your keystore.properties file into the keystoreProperties object.
keystoreProperties.load(new FileInputStream(keystorePropertiesFile))

android {
    ...
}

3.修改模块 build.gradle 文件的 signingConfigs 块

8

11
android {
    signingConfigs {
        config {
            keyAlias keystoreProperties['keyAlias']
            keyPassword keystoreProperties['keyPassword']
            storeFile file(keystoreProperties['storeFile'])
            storePassword keystoreProperties['storePassword']
        }
    }
    ...
  }

现在可以将 keystore.properties 从源代码控制系统中移除。

androidTest与test包的区别

本地单元测试(src/test/java)

这些测试在计算机的本地 Java 虚拟机 (JVM) 上运行。 当您的测试没有 Android 框架依赖项或当您可以模拟 Android 框架依赖项时，可以利用这些测试来尽量缩短执行时间。

仪器测试(src/androidTest/java)

这些测试在硬件设备或模拟器上运行。 这些测试有权访问 Instrumentation API，让您可以获取某些信息（例如您要测试的应用的 Context）， 并且允许您通过测试代码来控制受测应用。 可以在编写集成和功能 UI 测试来自动化用户交互时，或者在测试具有模拟对象无法满足的 Android 依赖项时使用这些测试。

Drawable xxx/ic_navigate_back has unresolved theme attributes! 
    Consider using Resources.getDrawable(int, Theme) or Context.getDrawable(int).

解决方法:

Drawable upArrow = ContextCompat.getDrawable(mContext,R.drawable.ic_navigate_back);

ContextCompat.getDrawable(Context, int) 代替 getResources().getDrawable(int)

Solutions include finding newer versions or alternative libraries that don't have the same problem 
(for example, for httpclient use HttpUrlConnection or okhttp instead), or repackaging the library using something like jarjar. [DuplicatePlatformClasses]

“BigDecimal(double)” should not be used

不要使用BigDecimal(double)去构造一个BigDecimal对象，因为double类型在计算机表示方法中并不精确，因此，BigDecimal(double)构造出来的对象很可能不是预期的大小，若一定要使用double类型去构造一个BigDecimal对象，请使用BigDecimal.valueOf方法，该方法先将double转换为String，再通过String构造BigDecimal对象，通常更建议使用public BigDecimal(String val)构造方法。

Noncompliant Code Example

1
2

4
double d = 1.1;

BigDecimal bd1 = new BigDecimal(d); // Noncompliant; see comment above
BigDecimal bd2 = new BigDecimal(1.1); // Noncompliant; same result

Compliant Solution

1

4
double d = 1.1;

BigDecimal bd1 = BigDecimal.valueOf(d);
BigDecimal bd2 = new BigDecimal("1.1"); // using String constructor will result in precise value
