Logcat empty using ACRA on device

问题

So I'm using ACRA 4.4.0 with all defaults, and my logcat field is empty.

My app has the

<uses-permission android:name="android.permission.READ_LOGS" />

permissions, which should at least give me my own app logs since Jelly Bean.

Final note: READ_LOG permission is not granted to third-party apps anymore since Android 4.1 (JellyBean). Starting with this version, logcat provides only traces from your own app, without requiring a permission. JellyBean logcat logs are retrieved by ACRA starting with version 4.3.0b2

So I do a forced log:

Log.i("mytag" , "message");
ACRA.getErrorReporter().handleException(null);

On the emulator (v4.2), I get the full logcat. (Which BTW is somewhat contradictory to the JB imposed logcat restriction)
However, on my device v4.2.1, the logcat is completely empty.

Anyone has any ideas?

回答1:

If you are using email-mode acra reporting (mailTo tag inside @ReportsCrashes) the LogCat field isn't included to decrease the report size. To get around this you just need to use the customReportContent tag.

(Took a while of searching before I found this - it is written in the documentation, just not in the section mentioning LogCat)

@ReportsCrashes(formKey = "",
    mailTo = "xxxx@yyyy.com",
    customReportContent = {ReportField.APP_VERSION_CODE, ReportField.APP_VERSION_NAME, ReportField.ANDROID_VERSION, ReportField.PHONE_MODEL, ReportField.STACK_TRACE, ReportField.LOGCAT },
    mode = ReportingInteractionMode.TOAST,
    resToastText = R.string.crash_toast_text
)

Note: I excluded the USER_CONTENT and CUSTOM_DATA field

Note2: import org.acra.ReportField;

I suppose it is because starting with JellyBean you cannot use READ_LOGS anymore. For further explanation read here:
