StrictMode.VmPolicy.Builder

StrictMode.VmPolicy.Builder ()

StrictMode.VmPolicy.Builder

StrictMode.VmPolicy.Builder (StrictMode.VmPolicy base)

Build upon an existing VmPolicy.

build

StrictMode.VmPolicy build ()

Construct the VmPolicy instance.

Note: if no penalties are enabled before calling build, penaltyLog() is implicitly set.

detectActivityLeaks

StrictMode.VmPolicy.Builder detectActivityLeaks ()

Detect leaks of Activity subclasses.

detectAll

StrictMode.VmPolicy.Builder detectAll ()

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.

detectCleartextNetwork

StrictMode.VmPolicy.Builder detectCleartextNetwork ()

Detect any network traffic from the calling app which is not wrapped in SSL/TLS. This can help you detect places that your app is inadvertently sending cleartext data across the network.

Using penaltyDeath() or penaltyDeathOnCleartextNetwork() will block further traffic on that socket to prevent accidental data leakage, in addition to crashing your process.

Using penaltyDropBox() will log the raw contents of the packet that triggered the violation.

This inspects both IPv4/IPv6 and TCP/UDP network traffic, but it may be subject to false positives, such as when STARTTLS protocols or HTTP proxies are used.

detectFileUriExposure

StrictMode.VmPolicy.Builder detectFileUriExposure ()

Detect when this application exposes a file:// Uri to another app.

This exposure is discouraged since the receiving app may not have access to the shared path. For example, the receiving app may not have requested the READ_EXTERNAL_STORAGE runtime permission, or the platform may be sharing the Uri across user profile boundaries.

Instead, apps should use content:// Uris so the platform can extend temporary permission for the receiving app to access the resource.

detectLeakedClosableObjects

StrictMode.VmPolicy.Builder detectLeakedClosableObjects ()

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.

detectLeakedRegistrationObjects

StrictMode.VmPolicy.Builder detectLeakedRegistrationObjects ()

Detect when a BroadcastReceiver or ServiceConnection is leaked during Context teardown.

detectLeakedSqlLiteObjects

StrictMode.VmPolicy.Builder detectLeakedSqlLiteObjects ()

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.

penaltyDeath

StrictMode.VmPolicy.Builder penaltyDeath ()

Crashes the whole process on violation. This penalty runs at the end of all enabled penalties so you'll still get your logging or other violations before the process dies.

penaltyDeathOnCleartextNetwork

StrictMode.VmPolicy.Builder penaltyDeathOnCleartextNetwork ()

Crashes the whole process when cleartext network traffic is detected.

penaltyDeathOnFileUriExposure

StrictMode.VmPolicy.Builder penaltyDeathOnFileUriExposure ()

Crashes the whole process when a file:// Uri is exposed beyond this app.

penaltyDropBox

StrictMode.VmPolicy.Builder penaltyDropBox ()

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.

penaltyLog

StrictMode.VmPolicy.Builder penaltyLog ()

Log detected violations to the system log.

setClassInstanceLimit

StrictMode.VmPolicy.Builder setClassInstanceLimit (Class klass, 
                int instanceLimit)

Set an upper bound on how many instances of a class can be in memory at once. Helps to prevent object leaks.
