Hi, all,
My device porting is almost complete and now I try to pass CTS test.
There are some strange issue that I do not know how to solve.
1. I know for JellyBean, the READ_LOGS permission are restricted to
system. But I still can read output from logcat in my device.
PackageManager pm = getPackageManager();
pm.checkPermission(Manifest.permission.READ_LOGS, getPackageName())
== PackageManager.PERMISSION_GRANTED))
the above code return false. Means my test apk does not contain
READ_LOGS permission. But I can still get log from logcat by the following
code:
logcatProc = Runtime.getRuntime().exec(new String[]
{"logcat", "-d", "ActivityManager:* *:S" });
reader = new BufferedReader(new
InputStreamReader(logcatProc.getInputStream()));
int lineCt = 0;
String line;
while ((line = reader.readLine()) != null) {
if (!line.startsWith("--------- beginning of /dev/log")) {
lineCt++;
}
}
lineCt is not zero. I have checked
my frameworks/base/core/res/AndroidManifest.xml
<permission android:name="android.permission.READ_LOGS"
android:permissionGroup="android.permission-group.DEVELOPMENT_TOOLS"
android:protectionLevel="signature|system|development"
android:label="@string/permlab_readLogs"
android:description="@string/permdesc_readLogs" />
Seems not unusually. I also check logcat source code but does
not find any thing check the permission.
2. InetAddress.getByName("www.yahoo.com"); need throw security
exception.
But it can pass on my device even the apk does not grant
android.permission.INTERNET and
Code base is android 4.2.1, any one have hint? Just don't know how
to debug such kind of issues.
