ANR when writing to file for 2nd time
I am logging errors to a file on the external storage of my device. The first time I write to the file it works no problem. However, the second time I get and ANR. Here is the code:
PrintWriter writer;
try {
writer = new PrintWriter(
new FileWriter(LOG_FILE_DIR + LOG_FILE, true)
);
while(e != null){
e.printStackTrace(writer);
e = e.getCause();
}
writer.println();
writer.println("--------------------------------------------------");
writer.flush();
writer.close();
} catch (IOException ex) {
ex.printStackTrace();
}
Here is the output from /data/anr/traces.txt:

Make your logging method synchronized to avoid problems with writing from several threads to one file

Doesn't seem to be a problem with your code, but note take that e.printStackTrace(writer); already does what you want, if the Throwable contains a cause, the method will be invoked recursively for the nested Throwable and print the corresponding stacktrace, making your while loop unnecessary.
You can try without the while loop and check that there is no cycle between the exceptions (that is if e and t are exceptions and e.getCause() is t then make sure and t.getCause() is different than e)
