Question

android怎么在release版下不输出日志

Answer 1

主要有两种方法：

方法一：如果有做代码混淆，在配置文件中加入下面语句

-assumenosideeffects class android.util.Log {

public static *** d(...);

public static *** v(...);

public static *** i(...);

}

方法二：对于没做代码混淆的，可以按照下面方法：

在manifest文件中加入android:debuggable="@bool/build_log"

android:name="MyApplication"

android:icon="@drawable/gift"

android:label="@string/app_name" android:debuggable="@bool/build_log">

定义一个日志类

public class Lol {

public static final boolean ENABLE_LOG = true & MyApplication.sDebug;

private static final boolean DEBUG = true & ENABLE_LOG;

private static final boolean VERBOSE = true & ENABLE_LOG;

private static final boolean TEMP = true & ENABLE_LOG;

private static final boolean WARNING = true & ENABLE_LOG;

private static final boolean INFO = true & ENABLE_LOG;

private static final boolean ERROR = true & ENABLE_LOG;

public static void obvious(String tag, String msg) {

if (DEBUG) {

msg = "*********************************\n" + msg

+ "\n*********************************";

Log.d(tag, msg);

}

}

public static void d(String tag, String msg) {

if (DEBUG)

Log.d(tag, msg);

}

public static void d(boolean bool, String tag, String msg) {

if (TEMP&bool)

Log.d(tag, msg);

}

public static void i(String tag, String msg) {

if (INFO)

Log.i(tag, msg);

}

public static void e(String tag, String msg) {

if (ERROR)

Log.e(tag, msg);

}

public static void e(boolean bool, String tag, String msg) {

if (TEMP&bool)

Log.e(tag, msg);

}

public static void v(String tag, String msg) {

if (VERBOSE)

Log.v(tag, msg);

}

public static void w(String tag, String msg) {

if (WARNING)

Log.w(tag, msg);

}

public static String getStackTraceString(Exception e) {

return Log.getStackTraceString(e);

}

public static void w(String tag, String msg, Exception e) {

if (WARNING)

Log.w(tag, msg,e);

}

}
