android里面的log输出以往都是在eclipse里面看,如果通过USB连接电脑,可以输出到PC上。
try {
//adb logcat -v threadtime > logcat.txt
String fileName = "logcat_" + System.currentTimeMillis() + ".txt";
File outputFile = new File(Environment.getExternalStorageDirectory(), fileName);
@SuppressWarnings("unused")
Process process = Runtime.getRuntime().exec(
"logcat -v threadtime -f" + outputFile.getAbsolutePath());
} catch (IOException e) {
}
bat:
adb logcat -v threadtime > logcat.txt
