| ↳ | android.os.StrictMode.VmPolicy.Builder |
Creates StrictMode.VmPolicy instances. Methods whose names start
with detect specify what problems we should look
for. Methods whose names start with penalty specify what
we should do when we detect a problem.
You can call as many detect and penalty
methods as you like. Currently order is insignificant: all
penalties apply to all detected problems.
For example, detect everything and log anything that's found:
StrictMode.VmPolicy policy = new StrictMode.VmPolicy.Builder()
.detectAll()
.penaltyLog()
.build();
StrictMode.setVmPolicy(policy);

Build upon an existing VmPolicy.
Construct the VmPolicy instance.
Note: if no penalties are enabled before calling
build, penaltyLog() is implicitly
set.
Detect leaks of Activity subclasses.
Detect everything that's potentially suspect.
In the Honeycomb release this includes leaks of SQLite cursors, Activities, and other closable objects but will likely expand in future releases.
Detect when a file:// Uri is exposed beyond this
app. The receiving app may not have access to the sent path.
Instead, when sharing files between apps, content://
should be used with permission grants.
Detect when an Closeable or other
object with a explict termination method is finalized
without having been closed.
You always want to explicitly close such objects to avoid unnecessary resources leaks.
Detect when a BroadcastReceiver or
ServiceConnection is leaked during Context
teardown.
Detect when an
SQLiteCursor or other
SQLite object is finalized without having been closed.
You always want to explicitly close your SQLite cursors to avoid unnecessary database contention and temporary memory leaks.
Crashes the whole process on violation. This penalty runs at the end of all enabled penalties so yo you'll still get your logging or other violations before the process dies.
Enable detected violations log a stacktrace and timing data
to the DropBox on policy
violation. Intended mostly for platform integrators doing
beta user field data collection.
Log detected violations to the system log.
Set an upper bound on how many instances of a class can be in memory at once. Helps to prevent object leaks.
