Android custom log log output tool, this tool class has the following advantages:
1 Fill in this in the first parameter of the LogUtlis method to output the name of the current class, especially in anonymous internal classes, you can also output the name of the current class.
Such as: (this,"This is a practical log tool class") or (class name.class,"This is a practical log tool class").
Effect: For example, I directly (this, "logTest") in MainActivity, and cooperate with my favorite logo, and the result can be output as
"zhang————MainActivity: logTest", convenient for debugging and reading logs.
2 You can use custom variables in the build file in AndroidStudio to control whether the output of different versions of logs is performed.
Steps to use:
1 Define the variable name in the app directory and write the project under make or build.
/**
* If buildConfigField under release is false, the log output will be blocked.
*/
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile(''), ''
buildConfigField "boolean","LOG_DEBUG","true"
}
debug{
minifyEnabled false
buildConfigField "boolean","LOG_DEBUG","true"
proguardFiles getDefaultProguardFile(''), ''
}
}
2 Define this in the onCreate method in the applied application
/**
* BuildConfig.LOG_DEBUG Get the custom log control variable
*/
if (BuildConfig.LOG_DEBUG) {
= true;
} else {
= false;
}
